HB_IO_NEW
Harwell Boeing Sparse Matrix Files
Read and Write Utilities


HB_IO_NEW is a C++ library which reads and writes files in the Harwell Boeing sparse matrix format. It is a version of HB_IO, revised by Reinhard Resch.

Reinhard Resch's improvements include

Note that the most common "flavor" of HB file is an assembled sparse matrix, but that there are some lesser used options, including storage of the matrix as unassembled finite element matrices, and corresponding storage of vectors. These secondary options are less well documented, and are only marginally supported in this package.
