When Intel visual Fortran call Pardiso in MKL to solve a linear equation group, you need to read the sparse matrix from the file. But there are many ways to store sparse matrices in files (such as: COO,CSR,CSC,DIO,et al.), and I want to find a library or package that can read and write sparse matrices.This library or package needs to meet two conditions: (1) There is a Fortran interface, (2) suitable for various sparse matrix storage methods. Or, what other methods do you have to solve the problem of reading and writing sparse matrices. I need your advice. Thank you.
