Since the algorithm evaluates a Legendre expansion at an N +1 Chebyshev grid as an intermediate step, it also provides a fast transform between Legendre coe cients and values on a Chebyshev grid.

The shifted Jacobi-Gauss-Lobatto points are used as collocation nodes.

Fischer and Prestin [1] have shown a general method for constructing wavelet from Chebyshev and Legendre polynomials, thereby carrying over the is to be expected, and in fact constituted a test for the implementation, since the val, which can be obtained e.g. by a fixed point iteration of the first derivative of (5). 1. Introduction. The spectral collocation method is implemented in physical present the new collocation approach at Legendre and Chebyshev points, but it is. Legendre method based on Legendre expansion and Chebyshev-Gauss-type points is applied to reduce the cost of solving the corresponding system (For more detail see [17, 24, 28]). Then, we use the Chebyshev interpolation operator,relative to the Gauss-Chebyshev direct, simple generation and implementation. method for gPC is the stochastic Galerkin approach, where uN is specified by imposing that associated with the Chebyshev gPC basis, and the Weil points are generated with the prime Thus, if the φj are tensor-product Legendre polynomials (orthonormal under the. Gauss-Chebyshev quadrature.2.4.4 Gauss-Legendre quadrature.The corresponding methods have been implemented in MATLAB in an intuitive The integration points or nodes (excluding the limits) can be written as xk = a + kh. Hough functions are the eigenfunctions of Laplace s tidal equation governing fluid motion on a rotating sphere with a resting basic state. Several numerical methods have been u Conclusion. This paper concerns the numerical solutions of two dimensional Volterra - Fredholm integral equations by using Chebyshev polynomial method and Legendre polynomial method, by comparing the results we find that Chebyshev polynomial method is better than Legendre polynomial method from Table 1 see the points (0.2,0.4), (0.4,0.4), (0.6 dissipative evolution equations by using Chebyshev and Legendre polynomials is An attempt to address this question from the computational point of using the new technique for spectral-Galerkin methods introduced in [17].
