gmm++ is a generic C++ template library for sparse, dense and skyline
matrices. It is built as a set of generic algorithms (mult, add, copy,
sub-matrices, dense and sparse solvers ...) for any interfaced vector
type or matrix type. It can be view as a glue library allowing
cooperation between several vector and matrix types. However, basic
sparse, dense and skyline matrix/vector types are built in Gmm++, hence
it can be used as a standalone linear algebra library
