Here is how I measured the spent time for QR: QR<MyMatrix> qr_h(A); qr_h.matrixQ(); qr_h.matrixR(); th = walltime(&t0); The program crashes at the initialization of qr_h with the message I posted. > Notice that i say unitary instead of orthogonal because i want support > for complex matrices. Ok. With complex I haven't done much tests, but the code should work. I will test and eventually correct the issues. |
