HB_TO_ST
Harwell Boeing Sparse Matrix File
converted to
ST Sparse Triplet File

HB_TO_ST is a MATLAB program which accepts the name of a file containing a sparse matrix in the Harwell Boeing Sparse Matrix File Format, and which reads that data and writes a corresponding Sparse Triplet (ST) file.

Usage:

hb_to_st ( 'hb_file', 'st_file' )

• 'hb_file' is the name of the Harwell Boeing file to be read.
• 'st_file' is the name of the Sparse Triplet file to be created.
