Hi, I get the following with build 4559 trace(mat(1,3,2,4,2,2))=1@#I need the trace function to fake the also broken norme() function using M:mat(1,2,3,4,2,2)@#norm_e(M):sqrt(trace(transpose(M)*M))Best regards, Martin Kraska Edited by moderator 04 July 2012 01:00:28(UTC)

BTW., trace() is reserved function for debugging purpose - trace evaluations through Output window - see trace()Regards, Radovan |

Hi, ok, that is just my fault, I expected trace to be the trace of a matrix, i.e. the sum of the diagonal elements. In fact, I have to use tr(), than everything works as expected: M=mat(1,2,3,4,2,2)@#sqrt(tr(transpose(M)*M))=sqrt(30)@#Thanks for the hints!
