plasma_matrix, a MATLAB library which demonstrates how a large sparse MATLAB matrix can be written to or read from a Harwell-Boeing sparse matrix file.

Source Code:

• plasma_matrix_test.m, calls all the tests.
• plasma_matrix_test.sh, runs all the tests.
• plasma_matrix_test.txt, the output file.

• plasma_matrix_test01.m, computes a plasma matrix, writes it to a file, and retrieves it.
• msm_to_hb_test01.hb, the HB file created by the test.

The first test uses N = 5.

• plasma_5_rua.txt, the Harwell-Boeing sparse matrix file.

The second test uses N = 100.
