cosi
Cosine by orthogonal interpolation for itau object.
Syntax
F = cosi(x)
Description
F = cosi(A) is a function to approximate by orthogonal interpolation
cos(A), where A is a matrix or an itau object.
Input
A = independent tau variable (itau object) or any matrix.
Output
F = polynomial approximation of cos(A) in [a, b] evaluated with
orthovalM (itau object: F.mat contains the matrix).

sini, cosi, sinhi, coshi, expi, logi and sqrti.
