scientific prototyping and technical computing
FreeMat is a free environment for rapid engineering and scientific prototyping and data processing. It is similar to commercial systems such as MATLAB from Mathworks, and IDL from Research Systems, but is Open Source.
FreeMat Portable works best with the PortableApps.com Platform
