mm_to_hb


mm_to_hb, a MATLAB code which reads the information stored in a Matrix Market file, and writes it to a corresponding Harwell-Boeing sparse matrix file.

It is conceivable that the Matrix Market file will include (unnecessary) information associated with zero entries of the matrix. MM_TO_HB will automatically drop such information from the Harwell-Boeing file that it creates.

Usage:

mm_to_hb ( 'input.mm', 'output.hb' )
where

Languages:

mm_to_hb is available in a MATLAB version.
