Hello,
I'm trying to solve a structurally symmetric problem, but for some reason, with the attached program, everything fails except if mtype = 11. Could you help me understand why please ? I've exported the matrix to MATLAB and max(sort(I) - sort(J)) = 0, so the matrix should be indeed structurally symmetric.
Thank you in advance.
