eMatrix is a lightweight matrix library developed in C++. EMatrix is designed to help solve engineering problems requiring linear algebra. eMatrix is OS independent and is fairly portable. New features include inv(A) and det(A).
For my purposes it works very well, but does need some cleaning up. As the author, what should one expect. That said. I will endeavor to make the cleaning up a priority this year as well as improve the documentation and portability as well.
