I want to solve the huge matrix of linear equations ,so I have to use the sparse matrix format to obtain my answers.

Hence,I use the imsl_f_lin_sol_gen_coordinate to solve the A*x=b

In order to obtain the x,I very expect to get the inverse of A.

So in the imsl_f_lin_sol_gen_coordinate how can I to obtain the inverse of A matrix??

Is the IMSL_RETURN_SPARSE_LU_FACTOR can complete my wishes?

I use the IMSL C Numerical Libraries version6.0

P.S.

the problem I met is sovling for x in a linear equation of A*x=b

A is a fixed huge matrix.

So I think to obtain the inverse of A ,then get the answer x=A(-1)*b one by one

That is a best way to get the answer.

thanks for your attention
