The method for the dgeMatrix class uses Ward's diagonal Pade' approximation with three step preconditioning. This function computes the exponential of a square matrix A, defined as the sum from r=0 to infinity of A^r/r!. Several methods are provided. The Taylor series and Padé approximation are very importantly combined with scaling and squaring.
