Hi, I'm trying to solve a probabilistic model finding the eigenvalues of a sparse matrix.
The idea is to compute the eingenvalue of value 1, but I have some problem when matrixes
become big..
The output of octave is
error: eigs: error -14 in dneupd
error: called from:
error: nowork.m at line 4, column 14
I attach three examples created in the same mode:
nowork.m: error
sometimes work.m: after many attempts octave gives me the correct results
work.m: always correct
my OS is gentoo, octave is version 3.2.3.
Thank you very much for your help,
Best regards
Nicola
