Both Matrix.h++ and Linpack.h++ are completely compatible with Rogue Wave's other C++ class libraries, Tools.h++ and Math.h++, which are accepted standards in the industry.
Matrix.h++ includes all the funtionality of Math.h++. For example: general matrices, vectors, statistics, complex numbers, Fast Forier Transformation (FFT's), etc. Matrix.h++ adds specialized matrix classes such as banded, symmetric, positive-definite, Hermitian, tridiagonal, etc. Because Matrix.h++ includes Math.h++, it can take advantage of Math.h++'s highly optimized low-level assembly routines, making it fast as well as graceful.
