Source Code:

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

• fem_io_test01.m tests FEM_READ by reading the ELL data.
• fem_io_test02.m tests FEM_WRITE by writing the TINY data.

ELL is an example of a 2D finite element model in which a scalar value is stored. This data was computed by the FREE_FEM_POISSON program and is read by FEM_READ.
