exp(G) Scilab Function exp(G)
NAME
exp - exponential, matrix exponential
CALLING SEQUENCE
exp(X)
PARAMETERS
X : a vector or a square matrix with real or complex entries.
DESCRIPTION
If X is a vector (or a
non-square
matrix) exp(X) is the (element-wise)
exponential of the entries of X, e to the X.
If X is a
square
matrix exp(X) is the matrix
exp(X) = I + X + X^2 /2 + ...
The computation is performed by first block-diagonalizing X and then apply-
ing a Pade approximation on each block.
