cosine_transform, a MATLAB code which demonstrates some simple properties of the discrete cosine transform (DCT).

- cosine_transform_test.m, calls all the tests;
- cosine_transform_test.sh, runs all the tests;
- cosine_transform_test.txt, the output file.

- cosine_transform_test01.m, applies the transform and then its inverse.
