[Octave-bug-tracker] [bug #58602] Octave hangup when multiplying large matrices

[Dmitri A. Sergatskov]

Follow-up Comment #1, bug #58602 (project octave):

If you are using a package build by a vendor (Ubuntu), 
you need to report all the problem to them first. 
Most likely the problem is with their packaging. 

In this particular case I suspect yuo have a broken blas (openblas) library.

It works for me:

octave:6> C = rand(29128,3);
octave:7> R = [1,0,0;0,0,-1;0,1,0];
octave:8> tic; C = C*R; toc
Elapsed time is 0.000710964 seconds.
octave:9> whos C
