Computing the Matriz Ezponential by Pade type-Lagrange Method

摘要：

In this paper, we introduce the Padé type-Lagrange approximation to the matrix exponential. The explicit formula for computing the matrix exponential is presented. It is shown by a numerical example that the accuracy of the approximation increases as the order or the node increases.
