expi

Exponential by orthogonal interpolation for itau object.


Syntax
   F = expi(x)

Description
   F = expi(A) is a function to approximate orthogonal interpolation the
   exp(A), where A is a matrix or a itau object.

Input
   A = independent tau variable (itau object) or any matrix.

Output
   F = polynomial approximation of exp(A) in [a, b] evaluated (with
       orthovalM) (itau object: F.mat contains the matrix).
