MatrixMath.h

/*
 *  MatrixMath.h Library for Matrix Math
 *
 *  Created by Charlie Matlack on 12/18/10.
 *  Modified from code by RobH45345 on Arduino Forums, algorithm from
 *  NUMERICAL RECIPES: The Art of Scientific Computing.
 *  Modified to work with Arduino 1.0/1.5 by randomvibe & robtillaart
 *  Made into a real library on GitHub by Vasilis Georgitzikis (tzikis)
 *  so that it's easy to use and install (March 2015)
