Readme for conjugateGradient-2.2

Conjugate Gradient Solver ========================= [![Build Status](https://secure.travis-ci.org/LeventErkok/conjugateGradient.png?branch=master)](http://travis-ci.org/LeventErkok/conjugateGradient) Sparse matrix linear equation solver, using the Conjugate Gradient algorithm: http://en.wikipedia.org/wiki/Conjugate_gradient_method. The method is applicable to matrices that are symmetric and positive definite. On hackage: http://hackage.haskell.org/package/conjugateGradient
