MATLAB User Area

This area is dedicated to scientists, engineers and others who use the power of MATLAB to solve data analysis problems every day. In order to help you out, we are providing this area where MATLAB users can exchange their code. The functions included here can be easily downloaded and you can start using them in minutes. Here we've posted user contributed functions along with some of our own work. You can also obtain free evaluation/demonstration licenses for our commercial software. See our software page for more information on these packages.

A note about support: These functions are supplied as-is and there is no guarantee that they will operate for your given application. We cannot provide support on these functions. A good number of these functions are now included in PLS_Toolbox and/or our other commercial products and we do offer full support for those products (including the free demo versions of that software). If you experience problems need assistance, we suggest you request a demo license.
