chol problem

[Mucsyr]

Hello,

I am making the migration from Matlab to Octave and am having a problem running "chol" on my Linux machine.  "ERROR: Missing CHOLMOD. Sparse cholesky factorization disabled" Using Octave on my windows operating systems does not give me this error.  Any ideas?

Thanks in advance

CHOLMOD is part of SuiteSparse (was UFSparse) from Tim Davis (Look it up)... This means that when Octave was built and installed SuiteSparse was not present. So this means that you as using chol on a sparse matrix.

So how did you get you copy of Octave? Did you build it yourself? If so what OS and if linux distribution are you running? If you didn't build it yourself how did you get it? With that information we might be able to suggest what your next steps are.

Thanks for your response.  I am running OpenSuSE 10.3 64 bit.  I used YaST to install GNU Octave 3.0.1-1.1 x86_64  from OpenSuSE repository download.opensuse.org/repositories/science/openSUSE_10.3

Then you should file a bug report with OpenSuSE and ask them to add a
dependency of Octave on SuiteSparse. See

http://www.cise.ufl.edu/research/sparse/SuiteSparse/

and Mandriva and Fedora (RPM distributions like SUSE) have RPMS already
available for this package.
