cost
Cosine by tau approximation for itau object.
Syntax
[F, e, n] = cost(x)
Description
F = cost(x) is a function to approximate by tau method cos(x), x in
[a, b].
Input
x = independent tau variable (itau object).
Output
F = polynomial approximation of cos(x) in [a, b] evaluated (with
orthovalM) in argument M = matrixM(x) (double matrix).
See also
sint, sinht, cosht, expt and logt.
