Speed up performance for a given matrix structure

Hi

If the logical structure (not actual values) of the matrix remains same, is there a way to avoid symbolic factorization stage for problems requiring large number of of linear system solutions?

Regards

Dinesh

Could you please direct me to an example to achieve this?

My problem involve solving many linear systems (to obtain solution to non linear system)

For example, I would like to solve

A1 x1 = b1

then

A2 x2 = b2

where A2 depends on x1, but the sparsity of A1 and A2 are the same (however I do not have A2 until I solve for x1)

Regards
