Please find here two files: the first one is the
umf4hb.f90 file that calls the C-interface to UMFPACK4.1. The second is
an addition that performs several sparse-matrix operations that can be
helpful with the use of UMFPACK:
- The code of umf4hb.f90 is here.
- The code for the sparse matrix utilities can be found
- The f90_kind.f90 module (used with the F-compiler)
We have also a site on heat transfer simulation
