fix LU for linear solvers

Asked by Nguyen Van Dang

Dear all,
In a loop, I am solving a linear system AX=b, where A is a given matrix and its value does not change. Is there any way to fix LU so that we can use it for all iterations?
Thanks,
Best regards,
Dang

The LUSolver has a parameter "reuse_factorization". If you set this to true, the solver will reuse the LU-factorization.
