26 Feb 2009 CUDA in a MATLAB MEX-file Integrating NVIDIA CUDA code with MATLAB using a C MEX-file Author: Eric Johnson

04 Feb 2009 CDF 9/7 Wavelet Transform 2-D image decomposition and reconstruction with cdf 9/7 wavelet proposed in jpeg2000 Author: Wang Tianhui

The performance is worse than Pascal's one. So I'm gonna stick with his version. Good job and nice implementation though.

25 Jun 2008 Faster 2D-Hadmard Tranform Fast 2D-Hadamard/Walsh Transform based on Simple Matrix Vector Multiplication Author: Andre x@y.z, Jos

The author has indeed fixed the code issues and added a understandable help section. Well done!

btw, the classname argument is never used in the code ...
23 Jun 2008 Faster 2D-Hadmard Tranform Fast 2D-Hadamard/Walsh Transform based on Simple Matrix Vector Multiplication Author: Andre S, Andre

Fixed, contains now documentation and also function has now a sec. parameter to specify ordering of the basis functions.
18 Jun 2008 Faster 2D-Hadmard Tranform Fast 2D-Hadamard/Walsh Transform based on Simple Matrix Vector Multiplication Author: Andre x@y.z, Jos

Files contains no proper help or internal comments. How do you expect others will be able to use this submission?

There are also some programming issues, e.g. log2(N) is computed multiple times.
