Languages:

General language examples include: a C version and a C++ version and a FORTRAN90 version and a MATLAB version and a Python version.

Source Code:

• py_test.sh, runs all the tests.

DATA_EXAMPLE shows how a computation can be set up in which certain problem-associated data can be defined by the user, and then later accessed by the computation. A class can be set up so that when a member of the class is created, data values may be associated with it and retrieved as needed, in a standard way. This avoids the use of static or global or persistent or common variables that are used in other languages.

• data_example.py, the source code.
• data_example.sh, runs all the test.
• data_example.txt, the output file.

HELLO is a simple example to print out "Hello, world!".

• hello.py, the source code.
• hello.sh, runs all the test.
• hello.txt, the output file.

HSTACK_TEST shows how two or more arrays of the same row dimension can be horizontally stacked.

• hstack_test.py, the source code.
• hstack_test.sh, runs all the test.
• hstack_test.txt, the output file.

MAIN_DEMO shows how a Python file can include text that only executes if the file is called directly, as a "main program". In that case, the text might, for instance, run a demonstration or test of the functions within the file.

• main_demo.py, the source code.
• main_demo.sh, runs all the test.
• main_demo.txt, the output file.

SUPPRESS_SPACES demonstrates that, when printing, you can suppress the spaces that are automatically inserted between successively printed items.

• suppress_spaces.py, the source code.
• suppress_spaces.sh, runs all the test.
• suppress_spaces.txt, the output file.

VSTACK_TEST shows how two or more arrays of the same column dimension can be vertically stacked.

• vstack_test.py, the source code.
• vstack_test.sh, runs all the test.
• vstack_test.txt, the output file.

• i4mat_print.py, prints an I4MAT.
• i4mat_print_some.py, prints some of an I4MAT.
• timestamp.py, prints the YMDHMS date as a timestamp.
