Problem with the transpose of SymMat about fmatvec

[foerg]

As transpose has no effect on symmetric matrices it was removed to prevent the user of applying an unnecessary operation. Do you really need the transpose operator for SymMat?
I would recommend to omit trans in your operation or to use the function JTMJ:
rotatedStiffness = JTMJ(stiffnessMatrix, randomRotationMatrix);

As matter of fact no, I don't need the transpose. I copied the code from another place (probably some old Matlab code) and did not put much thinking on it. Indeed now, looking at the code I realized it is wrong because I'm symmetrizing a non symmetric matrix. I'll correct it.

Thank you for informing the JTMJ function! I did not know it.

I'll close the issue.
