# SparseMatrix ## Synopsis SparseMatrix is a small C++ class to represent a sparse square matrix in compressed row format. It's very useful for FEM codes when coupled with a decent matrix solver (eg. Algebraic [Multigrid Method](http://en.wikipedia.org/wiki/Multigrid_method "Multigrid Method")). ## Explanation The SparseMatrix class stores matrix entries in compressed row format. That is, each each diagonal element is stored together with any non-zero off-diagonal elements. This makes it very memory efficient for storing large sparse matrices such as those used in the [finite element method](http://en.wikipedia.org/wiki/Finite_element_method "Finite Element Method"). I wrote this class as part of a job interview and thought I'd add open source it so that others might benefit. Much of the API is commented in [Doxygen](http://www.doxygen.org "Doxygen") format, and the class is templated for flexibility. A very basic solve method is also included for testing purposes. Testing is performed via [googletest](http://code.google.com/p/googletest/ "The Google C++ testing framework"), which you need to download and unzip into the main directory.
