expm
square matrix exponential
Calling Sequence
expm(X)
Arguments
- X
square matrix with real or complex entries.
Description
X is a square matrix expm(X) is the matrix
expm(X) = I + X + X^2 /2 + ...
The computation is performed by first
block-diagonalizing X and then applying a Pade approximation
on each block.
Examples
X=[1 2;3 4] expm(X) logm(expm(X))
