HB_READ
Simplified Harwell-Boeing Sparse Matrix File Reader


HB_READ is a FORTRAN90 library which reads files in the Harwell Boeing (HB) sparse matrix format. This is a simplified interface intended to handle only the most common format, complex unsymmetric assembled (CUA) or real unsymmetric assembled (RUA).
