Just want vector and matrix algebra and not the entire numerical algorithm kitchen sink? Don't care about FORTRAN? This may be for you. This package is a small, well-tested C++ library that provides basic addition, multiplication, and inversion.
Exactly what I was looking for! is there any other library with more linear algebra implementations and at the same time as simple as this one is. I don't care for any efficiency as of now. I just want to learn. I have already seen LAPACK and Eigen implementations but they are a bit too much to begin with.
