This directory contains the matlab function hilo.m and supporting scripts. 

Description
-----------

The hilo.m matlab function is used to process raw MOS capacitor high-low C-V
data into interface trap density vs. trap energy data using two different
methods: traditional high-low, and the C-psi technique. See the hilo.m comment
header for usage details and literature references. 

License
-------

These scripts are provided under the terms of the FreeBSD license, a copy of
which is located in the LICENSE file in the same directory.

Usage
-----

These matlab files should be placed in a directory accessible to MATLAB via it's
search path (see MATLAB documentation on 'path' or 'addpath' functions).

Scripts can be run from any working directory, so long as the filenames supplied
include sufficient path information.

The file 'example.m' along with the provided example high-low c-v data file
'data.csv' demonstrate typical usage of the hilo.m function. It imports the
data.csv file, translates it as needed, processes the data into interface trap
density, and writes the data to the directory "processed".

Other Files
-----------

The following additional matlab files are required for normal operation, and are
available at https://github.com/dtmorisette/MatlabUtilities:

GetConstants.m	Retrieves required universal physical constants.
GetMaterial.m	Retrieves required material properties.
FindLinearFit.m	Locates a "prevalent" linear section in the provided data and
		performs a linear fit to only that section.

The following scripts are optional but useful for import/export of raw C-V data:

ImportCSV.m		Imports a CSV formatted file into matlab. 
SaveAsCSV.m		Saves a matlab structure array to a CSV file.
TranslateData.m	Helper script that converts the structure imported by
ImportCSV
		to the format required by hilo.m. Should be modified as needed for
		other input CSV formats.

System specific info

This code was developed under MATLAB R2012b (8.0.0.783) on OS X 10.9. Operation
on other systems or versions of MATLAB may work but are not officially
