Type ii dct, improvement to matlab's dct

The following Matlab project contains the source code and Matlab examples used for type ii dct, improvement to matlab's dct . This code does the same as matlab's dct with a few improvements: 1) on the first call, it's a bit faster than the builtin dct 2) on subsequent calls, due to persistent variables, it's about 2x or more faster than the builtin dct, and only about 1.

The source code and files included in this project are listed in the project files section, please make sure whether the listed source code meet your needs there.
