Description

Defines a function, MatrixExp1, to compute the matrix exponential of a square matrix A. This function replaces MatrixExp if Precision[A] is equal to Infinity.

In this case, the evaluation of MatrixExp1[A] often requires considerably less CPU time than the evaluation of MatrixExp[A]. A reduction of the CPU time was observed, in particular, when the order of A was large or the entries of A had a variable as a common factor.
