Source Code:

• r8mat_print.py, prints an R8MAT.
• r8mat_print_some.py, prints some of an R8MAT.
• r8vec_print.py, prints an R8VEC.
• timestamp.py, prints the current YMDHMS date as a timestamp.

Examples and Tests:

• r4lib_test.py, a program that calls all the tests.
• r4lib_test.sh, a BASH shell script that executes the test program.
