## rtau

Class to rigth member of tau problem.

Class to rigth member of tau problem.

classdef rtau

r = rtau(basis, domain, n) creates an object r called rigth member of tau method.

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.

r = rigth member of tau method (rtau object).

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.
