## Matrix Template Library

While rewriting some data analysis software I developed many years ago (the original was written in K & R C, the new version will be written in C++), I stumbled upon The Matrix Template Library (MTL). MTL is a library that provides comprehensive linear algebra functionality for a wide variety of matrix formats. I was … Continue reading “Matrix Template Library”

## Two Free Computer Algebra Systems

A few months ago I was looking for a free computer algebra system (CAS). For some reason (probably I wasn’t really looking hard enough), I didn’t find anything that the bill. Yesterday, while updating Cygwin on my Windows box at work, I saw a link to something called Mathomatic. I turns out that Mathomatic is … Continue reading “Two Free Computer Algebra Systems”
