Syntax

   F = coshi(x)

Description

   F = coshi(A) is a function to approximate by orthogonal interpolation 
   cosh(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 cosh(A) in [a, b] evaluated with
       orthovalM (itau object: F.mat contains the matrix).
