Alex, FYI, your example is working fine for me: >> load test.mat >> A2 = sparsersb (A); >> extx2 = sparsersb (extx); >> x2 = A2 * extx2; >> [ia, ja, va] = find (A); >> [ie, je, ve] = find (extx); >> A3 = sparsersb (ia, ja, va); >> extx3 = sparsersb (ie, je, ve); >> x3 = A3 * extx3; What version of Octave are you using? how did you install sparsersb? c. ------------------------------------------------------------------------------ RSA(R) Conference 2012 Save $700 by Nov 18 Register now http://p.sf.net/sfu/rsa-sfdev2dev1 _______________________________________________ Octave-dev mailing list Octave-dev@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/octave-dev
