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