- %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.
- % See EXPM1, EXPM2 and EXPM3 for alternative methods.
- %
- % EXP(X) (that's without the M) does it element-by-element.
