Just wanted to contribute back some changes that I made:

https://github.com/diffplug/matlabcontrol

Added CopyPasteCallback to the set of options for creating a 
MatlabProxyFactory. The factory sends a chunk of code to the callback, and the 
user copy-pastes this code into a MATLAB terminal to initiate a connection.

ThrowableWrapper now initializes the getMessage() field with MATLAB's raw error 
text.

Added OSGiClassloaderFriendly to the set of factory options. When this flag is 
set to true, RMI is started in a way that doesn't get hosed by OSGi.

The CopyPasteCallback is very handy for implementing interactive applications 
such as this:

What did you expect to happen? What happened instead?
I expected to get some sub matrix and get the median array of the sub matrix. 
For matrix of smaller size, it works fine. 

If there was a stack trace, please copy it here.


Please provide any additional information below.

What version of matlabcontrol are you using?
4.0.0


What version of MATLAB are you using?
2010b 32bit


What operating system are you using?
10.8.0 Darwin Kernel Version 10.8.0


Are you using matlabcontrol from inside MATLAB or outside MATLAB?
outside


What steps will reproduce the problem?
1.  Create two MatlabProxy connections from outside matlab, and make sure they 
are connected.
2.  Invoke a matlab function on the first MatlabProxy that blocks and does not 
return.
3.  Invoke a matlab function on the second MatlabProxy.

What did you expect to happen? 
Expected second MatlabProxy to also invoke its method in step 3, without 
requiring the first MatlabProxy to finish.

What happened instead?
The code blocks until the first MatlabProxy function is completed, and the 
MatlabProxy does not finish.

Please provide any additional information below.

I am trying to start two processes that run at the same time in Matlab.  Since 
neither process do not return a value and instead are continually running, I am 
unable to start both processes using MatlabControl.

Is this right?  Or, did I miss an option somewhere?

What version of matlabcontrol are you using?
(Release versions: 4.1.0, 4.0.0, 3.1.0, 3.0.1, 3.0.0, or 2.0.0)
4.1.0

What version of MATLAB are you using?
R2011b

What operating system are you using?
OSX

Are you using matlabcontrol from inside MATLAB or outside MATLAB?
Outside

What steps will reproduce the problem?
1. Run the following sample code:
MatlabProxyFactory factory = new MatlabProxyFactory();
MatlabProxy proxy = factory.getProxy();

proxy.eval("disp('hello world')");

// Use the proxy as desired
System.out .println("disconnected: " + proxy.disconnect());

What did you expect to happen? What happened instead?
I would expect disconnect to print as true based on the javadoc.. but it prints 
as false.

If there was a stack trace, please copy it here.


Please provide any additional information below.
It looks like RemoteMatlabProxy#disconnect() returns #isConnected(), which is 
the reverse of what the javadoc suggests.

I am not sure if there are any other implications of this flag being flipped.

I'm using matlabcontrol 4.0.0, Matlab r2010a on Debian Squeeze.
I'm using MatlabControl from outside MATLAB. The client class is a class 
running inside a Tomcat 6.0 (the one in the Debian repository!).

At the attempt of calling the MATLAB instance, no error is catched, but the 
connection time out!

This problem happens only if Tomcat is running as a service. If Tomcat is 
launched from the shell everything works fine.

Thinking it was a security problem, I tried to grant all security permissions 
to the web application but nothing changed.
I thought it could be related to the PATH environment variable, but the PATH 
variable maps the MATLAB codebase location and nothing good happened.
Files permissions are OK.

Am I forgetting something?

Thanx

Rudy

Following the documentation I first tried:

MatlabProxyFactoryOptions options = new MatlabProxyFactoryOptions.Builder()
options.build();
options.setHidden(true);

The error is: type mismatch and if the type of options is changed to builder:

Builder options = new MatlabProxyFactoryOptions.Builder();
options.build();
options.setHidden(true);

There are no errors, however none of this options takes into effect.

Then I tried:

MatlabProxyFactoryOptions.Builder options = new 
MatlabProxyFactoryOptions.Builder();
options.build();
options.setHidden(true);

no errors but matlab does not run hidden again

What steps will reproduce the problem?
I am making a HelloWorld java program. Here is my source code:

import matlabcontrol.MatlabConnectionException;
import matlabcontrol.MatlabInvocationException;
import matlabcontrol.MatlabProxy;
import matlabcontrol.MatlabProxyFactory;
import matlabcontrol.MatlabProxyFactoryOptions;

public class HelloWorld

  MatlabProxyFactoryOptions options= 
    new MatlabProxyFactoryOptions.Builder()
        .setMatlabLocation("/usr/local/MATLAB/R2010b/bin/matlab")
    .build();
    //Create a proxy, which we will use to control MATLAB
  MatlabProxyFactory factory = new MatlabProxyFactory(options);
  MatlabProxy proxy = factory.getProxy();

    //Display 'hello world' just like when using the demo
  proxy.eval("disp('hello world')");

    //Disconnect the proxy from MATLAB
  proxy.disconnect();
}
}

What did you expect to happen? What happened instead?
I thought it would display Hello World in the new session of Matlab or the 
interface that would come up but instead I get this:

Are you using matlabcontrol from inside MATLAB or outside MATLAB?
Outside MATLAB.  Specifically, from a custom-written Java plugin in the 
Java-based microscopy software MicroManager.


What steps will reproduce the problem?
1. Creating a MatlabProxyFactoryOptions instance.

I expected Matlab would open, create an instance, and then I would later be 
able to connect to that instance.  When I create an instance, I get the error 
message below in Matlab.  Commands sent through the proxy will execute, but I 
cannot reconnect to the session.

What did you expect to happen? What happened instead?


Please provide any additional information below.
I use proxy.returningFeval to invoke a matlab function which returns 2 
parameters, numeric arrays. How can I get this values in JAVA?

What version of matlabcontrol are you using?
Release version: 4.0.0

What version of MATLAB are you using?
2011a 64-bit

What operating system are you using?
Windows 7 64-bit

Are you using matlabcontrol from inside MATLAB or outside MATLAB?
Outside in a Java application

What steps will reproduce the problem?
1. Run this code:

MatlabProxyFactoryOptions MATLABOptions = new 
MatlabProxyFactoryOptions.Builder().setHidden(true).build();
MatlabProxyFactory factory = new MatlabProxyFactory(MATLABOptions);
MatlabProxy proxy = null;
MatlabTypeConverter converter = null;
try
{
    proxy = factory.getProxy();
    converter = new MatlabTypeConverter(proxy);
    proxy.eval("a = [1+1i;2+2i;3+3i];");
    double[][] arrayRealValues = converter.getNumericArray("a").getRealArray2D();
    double[][] arrayImagValues = converter.getNumericArray("a").getImaginaryArray2D();
}
catch (Exception e)
{
    System.err.println(e);
}  


What did you expect to happen? What happened instead?
Expected to be able to access the variable in matlab without throwing an 
exception. The following message/exception was displayed instead:

"matlabcontrol.MatlabInvocationException: RuntimeException occurred in 
MatlabThreadCallable, see cause for more information"

The cause was indicated as: "java.lang.ClassCastException: [Ljava.lang.Object; 
cannot be cast to [D"

Please provide any additional information below.

Note that the above program works perfectly if accessing a real valued 
variable, i.e. if the eval line was adjusted to "proxy.eval("a = [1;2;3];");", 
and the getImaginaryArray2D command was removed.

Is this an entirely new feature or an enhancement of an existing feature?
Enhancement of existing feature,

What is the feature or enhancement?
I want an option added to change the architecture.  Right now when I try to 
start matlab through the proxy it fails to start because the default arch is 
64-bit because I have 10.6.8, but matlab is MATLAB_R2010aSV, which has no 
32-bit mac version.  The only way I've found to launch it is using this script 
and pointing the proxy towards it:

matlab.sh:
#!/bin/bash
shift
"/Applications/MATLAB_R2010aSV.app/bin/matlab" -maci "$@"

I don't say the script is perfect.  It might be dropping an argument, but that 
should give you an idea of what I mean.


If you have currently implemented a solution of your own to implement this
feature or enhancement, how have you done so?

I could probably do this if I needed to, though I don't see any build scripts, 
project files, or hints on how to build it, which would be a little annoying to 
do.  Or does this need something from MATLAB to build?

Please provide any additional information below.
This can be avoided by altering the port used when the RMI registry is created, 
so as to ensure the port is unique to the running process.

Is this an entirely new feature or an enhancement of an existing feature?

  I haven't been able to find a repo distributing compiled jars for this project.  This would be a handy thing to have, as it would make listing it as a dependency in projects using maven/lein/gradle etc.  easier.

What is the feature or enhancement?

  The enhancement would be to upload this project to a repo like Central (http://central.sonatype.org/).  This would make it easier for other projects to make use of matlabcontrol as a dependency, by listing the library in their build scripts for maven, ant, etc to download.

If you have currently implemented a solution of your own to implement this
feature or enhancement, how have you done so?

  I haven't done anything on this.  As I understand, sonatype will provide free hosting in their repo for open source projects, but there's a somewhat long-winded approach involved in getting this done -- see http://central.sonatype.org/pages/ossrh-guide.html

What version of matlabcontrol are you using?
(Release versions: 4.1.0, 4.0.0, 3.1.0, 3.0.1, 3.0.0, or 2.0.0)

What steps will reproduce the problem?
1. Edit DemoFrame.java to wrap the proxy with a LoggingMatlabProxy
         _proxyHolder.set(new LoggingMatlabProxy(proxy));

2. Run the demo, connect to matlab, select feval
3. Enter fprintf for function
4  For argument, select string and enter blah\n

What did you expect to happen? What happened instead?

Expected "blah" to be printed to matlab console, as it is when the 
LoggingMatlabProxy is not used.

Instead, it throws the following exception and displays an error in the matlab 
console.

What version of matlabcontrol are you using?
(Release versions: 4.1.0, 4.0.0, 3.1.0, 3.0.1, 3.0.0, or 2.0.0)
4.1.0

What version of MATLAB are you using? R2011b


What operating system are you using? Windows 8.1


Are you using matlabcontrol from inside MATLAB or outside MATLAB? outside MATLAB


What steps will reproduce the problem?
1. Run the demo java code
2.the matlab opens
3. run again the demo java code and a new matlab opens

What did you expect to happen? What happened instead?

I expect to open Matlab only one time but according to comments here, changing 
the code bellow would fix the problem:

MatlabProxyFactoryOptions options = new 
MatlabProxyFactoryOptions.Builder().setUsePreviouslyControlledSession(true).buil
d(); 

I changed but when java is run, a new matlab window is opened.

What operating system are you using? Windows XP


Are you using matlabcontrol from inside MATLAB or outside MATLAB? Outside


What steps will reproduce the problem?
1.In the Builder, set setHidden to true and use setMatlabStartingDirectory to 
set a starting folder.

What did you expect to happen? What happened instead? I expected a minimized 
command window opened in the starting folder I specified. However, the 
minimized command opened at the location where the Matlab executable was 
present. Hence, it was unable to execute a Matlab script present in the 
location specified by me as it never opened in that location. As a workaround, 
I manually pass a 'cd' command to the proxy to switch to the desired folder and 
then execute the script.

What did you expect to happen? What happened instead?


Please provide any additional information below.

Sometimes matlabproxy.eval(cmd) runs the command inside a method namespace 
instead of the main namespace. This happens in a gui matlab application, and 
I'm guessing it's related to callback functions. I expected this to not be 
possible due to matlab's single-threading, but I can see it happen occasionally.

Anyway: Replacing "eval" with "evalin","base" in the three relevant functions 
of JMIWrapper.MatlabThreadOperations seems to fix it.

New facade for existing matlabcontrol code


Implementation of the JSR-223 API


We (CSIRO Marine and Atmospheric Research) are using Matlabcontrol as a JSR-223 
bridge to Matlab from our code, this lets us treat Matlab as just another 
execution engine like other JVM based languages such as JRuby, Groovy, Jython 
(we also use native code based bridges to R and Perl). Implementing the JSR-223 
API in Matlabcontrol will ease its adoption into existing systems. We can 
contribute the JSR-223 bindings under MIT licence from our nascent TrikeND 
(http://sourceforge.net/projects/trikend/) project to be maintained within 
Matlabcontrol.

What version of matlabcontrol are you using?
(Release versions: 4.0.0, 3.1.0, 3.0.1, 3.0.0, or 2.0.0)
4.0.0

What version of MATLAB are you using?
R2009a

What operating system are you using?
Windows Vista Home Edition 64-bit

Are you using matlabcontrol from inside MATLAB or outside MATLAB?

outside

What steps will reproduce the problem?
1.  Downloaded matlabcontrol src package
2.  Created new project in JAVA named MatlabeControlGage.
3.  Modified the import commands and commands calling for "matlabcontrol" to 
"matlabcontrolgage" as was named.
4.  Reproduced the code at the following site:
http://code.google.com/p/matlabcontrol/wiki/Walkthrough

under the "Hello World" section.
5. Try to run the file named MatlabControlGage.java 
What did you expect to happen? What happened instead?
Expected to see display in tutorial "hello world"
Instead, got MATLAB to open with a display in the JAVA window of the following:
"
