%EXPM   Matrix exponential.
%   EXPM(X) is the matrix exponential of X.  EXPM is computed using
%   a scaling and squaring algorithm with a Pade approximation.
%
%   Although it is not computed this way, if X has a full set
%   of eigenvectors V with corresponding eigenvalues D, then
%   [V,D] = EIG(X) and EXPM(X) = V*diag(exp(diag(D)))/V.
%
%   EXPM1, EXPM2 and EXPM3 are alternative methods.
%
%   EXP(X) (that's without the M) does it element-by-element.
