MSM_TO_HB
Matlab Sparse Matrix
converted to
Harwell Boeing Sparse Matrix File

MSM_TO_HB is a MATLAB library which accepts a Matlab sparse matrix and writes it to a file in the Harwell Boeing (HB) Sparse Matrix File Format, by Xiaoye Li.

HB_IO, a MATLAB library which reads and writes sparse linear systems stored in the Harwell-Boeing Sparse Matrix format.

HB_TO_MSM, a MATLAB program which converts a Harwell Boeing sparse matrix to MATLAB sparse matrix format.

MM_TO_HB, a MATLAB program which reads the sparse matrix information from an MM Matrix Market file and writes a corresponding HB Harwell Boeing file.

MM_TO_MSM, a MATLAB program which reads a Matrix Market file defining a sparse matrix, and creates a corresponding MATLAB sparse matrix data structure.

MSM_TO_MM, a MATLAB program which writes a MATLAB sparse matrix to a Matrix Market (MM) file;

ST_TO_HB, a MATLAB program which converts a sparse matrix file from ST format to Harwell Boeing (HB) format;

TEST_MAT, a MATLAB library which defines test matrices with known inverses, determinants, eigenvalues and so on.

Source Code:

• msm_to_hb.m, writes a MATLAB Sparse matrix to a Harwell Boeing Sparse Matrix File.
• timestamp.m, prints the current YMDHMS date as a timestamp.

Examples and Tests:

• msm_to_hb_test.m, runs all the tests.
• msm_to_hb_test_output.txt, the output file.
• msm_to_hb_test01.m, tests MSM_TO_HB on a simple 5 by 5 matrix.
• msm_to_hb_test01.hb, the HB file created by the test.
