Hi, Can somebody please tell me if there is any Fortran equivalent to Suitesparse by Dr.Tim Davis Suitesparse . This is basically a library for handling sparse matrices. It is written in ‘c’. I am confused seeing all the pointer magics they do in ‘c’. So I am looking for a fortran alternative. Matla…

I’m not familiar with using suitesparse, but here are some possible Fortran options: [image] ivan-pi/SMMP Sparse matrix multiplication package. Contribute to ivan-pi/SMMP development by creating an account on GitHub. [image] ivan-pi/y12m Solution …

Thank you. Yeah, I don’t expect them to be as convenient.

UMFPACK is part of SuiteSparse and has a Fortran interface .

Hello @Ashok , based on your initial post, it seems that you are looking for direct sparse solvers. The ones I am aware of include: UMFPACK y12m SuperLU (in C) MUMPS MA48 PARDISO Intel MKL PARDISO Intel MKL Direct Sparse Solvers Most of these libraries offer a very low-level interface and expect…

The derived type shown above is very similar to the record structure used to store sparse matrices in MATLAB or the CSparse library (part of SuiteSparse). Specifically, for MATLAB, … A sparse matrix is a C record structure with the following constituents. The nonzero elements are stored in a one …

Thanks a lot @ivanpribec . The collection that Jack Dongarra has, many are written in Fortran. Unfortunately they are not modernized. That’s why c++ took up.

Yousef Saad’s SPARSKIT2 software is still available. It’s only Fortran 77 but I think John Burkhardt has an F90 translation on his site. It has the basic sparse BLAS routines along with translation to/from various sparse matrix formats. Also, some of his Newton-Krylov (GMRES etc) routines if I re…

Modern does not automatically means better. I benchmarked many of libraries mentioned and the winner was y12m.

@Jamie , @rwmsu , @themos , @Beliavsky Thank you. I will go through them and see what suits best to my use case.
