An alternative approach is given for linear-system reduction by Padé approximation to allow retention of dominant modes. It avoids calculation of system time moments and the solution of Padé equations by simply dividing out the unwanted pole factors. The resulting algorithm is conceptually simple and is seen to be of use in other methods of reduction.
