5.4 is out

Thank you for maintaining this project on github. Would be nice if 5.4 could be added.

accessing SPQR_qmult from C

In https://github.com/jluttine/suitesparse/blob/master/SPQR/Source/SuiteSparseQR_qmult.cpp there are functions to apply a Q factor to a dense or sparse matrix. But in this header file:

suitesparse/SPQR/Include/SuiteSparseQR_C.h

Line 196 in 003319c

returned by SuiteSparseQR_C_factorize) to a dense matrix X.

the description says SuiteSparseQR_C_qmult applies only for the dense case. Is there is no C interface for applying Q to a sparse matrix? Or am I missing something?

link dead

The link of the official repository is actually dead.

cannot find -lmetis during 'sudo make install INSTALL=/usr/local'

I am trying to compile SuiteSparse on Ubuntu 14.04.
I ran make in the suitesparse directory and i ran without erros.
In the bin folder I have the following executables:

/home/gunshi/Downloads/SuiteSparse/bin/cmpfillin
/home/gunshi/Downloads/SuiteSparse/bin/gpmetis
/home/gunshi/Downloads/SuiteSparse/bin/graphchk
/home/gunshi/Downloads/SuiteSparse/bin/m2gmetis
/home/gunshi/Downloads/SuiteSparse/bin/mpmetis
/home/gunshi/Downloads/SuiteSparse/bin/ndmetis

I can also see libmetis.so inside /home/gunshi/Downloads/SuiteSparse/metis-5.1.0/build/Linux-x86_64/libmetis

On trying to do :
sudo make install INSTALL=/usr/local

I get:

Any idea on how I can get it to install correctly?
Thanks.

Errors in compling SPQR with gcc6 + cuda 9

When I compile SuiteSparse with gcc 6 and cuda 9 I got these error messages.

SuiteSparse is officially on Github now

When you google suitesparse github this repo is the first result.
It was created as a mirror for SuiteSparse when SuiteSparse wasn't available on Github.
But now Tim Davis put it officially here: https://github.com/DrTimothyAldenDavis/SuiteSparse.
Keeping this repo only causes confusion. Please consider it for deletion.
Thank you.

Errors in compiling CHOLMOD

Hi,
I tried compiling using make, with "make BLAS=-lopenblas". I get the following errors. I've tried on two Linux PCs running Ubuntu and the same happens in both. I'm using the most recent release version.

Sparse constructs return uninitialized elements

Hi everyone,

I am working on graph analytics with my Master's student, @Lehel44.

When using GraphBLAS, we encountered some strange behaviour, documented in the code snippet below. We are beginners with GraphBLAS, so it's possible that we use the API incorrectly -- please advise on what changes we should make. We are aware that this is not an official repository, but it might be a good place to start.

Thank you.

#include "GraphBLAS.h"

    GrB_Index size;
    GrB_Vector_size(&size, vec);

        GrB_Vector_extractElement(&element, vec, i);
        printf("%lf ", element);
    }
    printf("\n");

Problem compiling without METIS

I tried to compile without METIS. To accomplish this, I set CONFIG_PARTITION to -DNPARTITION, as indicated in Suitesparse_config.mk. The problem is that the variable LIB_WITH_PARTITION should be cleared and it is not happening. Thus, the Makefile in CHOLMOD/Lib keeps using it and tries to ling with metis anyway.

I think the problem is in line 53 of Suitesparse_config.mk

ifeq (,$(findstring -DNPARTITION, $(CHOLMOD_CONFIG)))

that should be

ifeq (,$(findstring -DNPARTITION, $(CONFIG_PARTITION)))

Doing this modification, I could compile successfully.

Am I doing something wrong or it is indeed a mistake.

Thanks.

CSparse: type lnz from double to integer

Hello,

In according to code of CSparse, variable lnz, unz

suitesparse/CSparse/Include/cs.h

Line 68 in 306d7f1

double lnz ; /* # entries in L for LU or Cholesky; in V for QR */

Is should have integer type as LONG, but not float type DOUBLE.

Could you clarify ?

Thank you.
