Or the right side doesn't matter? If you have any matrix that might fail, write it here, so I'll try to make a testcase from it. The testFuzzySpase testcase was intented to test such problems, see here: < http://ktechlab.git.sourceforge.net/git/gitweb.cgi?p=ktechlab/ktl-zoltan_p;a=blob;f=matrixtest/matrixtester.cpp;h=f009b87ec0492e20c8d2ae9295659594c2058b1b;hb=testing-1#l360 > Strange.. It seems that this test somehow didn't made it to Julian's kde4-port branch. ------------------------------------------------------------------------------ Download Intel® Parallel Studio Eval Try the new software tools for yourself.
