Source Code:

• pbma_example.m, a function that creates a set of bit map data.
• pbma_read.m, a function that reads an ASCII PBM file.
• pbma_write.m, a function that writes an ASCII PBM file.
• pbma_write_test.m, creates an example dataset and writes it to an ASCII PBM file.

Examples and Tests:

• pbma_io_test.m, calls all the test routines.
• timestamp.m, is an auxilliary routine used by the tests.
• pbma_io_test_output.txt, the printed output from a run of the test.
• pbma_io_test01.m tests PBMA_EXAMPLE and PBMA_WRITE.
• pbma_io_test02.m, tests PBMA_READ.
