Obtaining CSR Format from a Given Symmetric Sparse Matrix

Question

I am very new to the use of sparse matrices for solving simultaneous equations. I want to use them for solving problems in FEA.

Is there a FORTRAN routine, or a function in the Intel Math Kernel library from which I can obtain the compressed row format (CSR) for a given symmetric matrix?

I can then use the CSR to solve my system of linear equations using the 'pardiso' routine in the Fortran MKL.

Thanks!
