Solve with L / Mutiplication with L (Cholesky factorization)
Hi, in the previous releases of pastix (5.xx), it was possible to solve independently
L x = b
or
L^T x = b
for the Cholesky factorisation. It was also possible to perform a multiplication by the factor L (or L^T) with the following parameters :
iparm[IPARM_TRANSPOSE_SOLVE] = API_SOLVE_BACKWARD_ONLY;
iparm[IPARM_TRANSPOSE_SOLVE] = API_SOLVE_FORWARD_ONLY;
iparm[IPARM_TRANSPOSE_SOLVE] = API_SOLVE_UTRMV;
iparm[IPARM_TRANSPOSE_SOLVE] = API_SOLVE_LTRMV;
How is it possible to perform these tasks with the new version of pastix (6.xx) ? Thanks for your help.
