A New Approach to Matriz Pade-type Approzimant

摘要：

A matrix Pade-type approximant MPTA was defined in 2 by introducing a generalized linear functional in the inner product space. In this note we derive an improved MPTA whose coefficients of the numerator polynomials are determined by coefficients of the denominator polynomials. On the basis of this result, an complete algorithm computing MPTA is given and an example for the matrix exponential isillustrated.
