Syntax

  classdef itau

Description

   x = itau(basis, domain, n) creates an object x called independent
   tau variable. 

Input

   basis  = orthogonal polynomial basis.
            'ChebyshevT' to Chebyshev of first kind, 
            'ChebyshevU' to Chebyshev of second kind, 
            'LegendreP' to Legendre, 
            'HermiteH' to Hermite,
            'LaguerreL' to Laguerre and
            'GegenbauerC' to Gegenbauer.
   domain = domain [a b], same interval of orthogonality of the basis.
   n      = dimension of the truncated matrices. 
            polinomial basis will have degree n-1.
   alphaC = parameter for Gegenbauer polynomials.

Output

   x = independent tau variable (itau object).

Examples

   x = itau('LegendreP', [0 10], 100) .............. customized inputs.
   x = itau('LegendreP', [0 10]) ............................... n = 5.
   x = itau('LegendreP') ................... domain = [-1 1] and n = 5.
   x = itau .......... basis = 'ChebyshevT', domain = [-1 1] and n = 5.
