What is it?

The Gnatlab program is designed to be a tool for fast matrix manipulation and calculation using the Matrix Template Library. It is designed to be easily expandable, with a simple programming interface. It uses the Matrix Template Library to do the calculations and it interfaces with the MTL in such a way that updates and changes to the MTL can be quickly incorperated into the program. Gnatlab aims towards the full functionality of similar commerical products.
