### Legende-Gauss-Lobatto nodes and weights

... script computes the nodes and weights for Legendre-Gauss-Lobatto quadrature as well as the LGL-vandermonde matrix for spectral ... which include the endpoints. For pure Gauss quadrature, Chebyshev is numerically better and has ... lower Lebesgue constant then Legendre, however, the opposite is true for ... Gauss-Lobatto quadrature. Demands ...

... Differential Quadrature Matrix for 1st derivative based on Lobatto grid.It calculates for ... grid points.Higher derivatives can be easily calculated by using ... MATLAB Release: R13SP1 ...

... This script computes the nodes and weights for Legendre-Gauss-Radau quadrature as well as the LGR-vandermonde matrix for ... fixed abcissa at ... -1. See also my scripts for Gauss and Lobatto quadrature using Legendre polynomials. Demands ...

### Legendre Collocation Differentiation

... This script computes the Legendre-Gauss-Lobatto nodes and the corresponding Legendre differentiation matrix. For ... some problems, Legendre gives faster convergence than Chebyshev. Useful for spectral methods. Demands ... MATLAB Release: R12 ...

### Weighted Grid Points

... and this script constructs the family of polynomials which are orthogonal with respect to the weight.Then ... the extrema of the highest polynomial are computed. Examples ... gives the Legendre Lobatto points and ... gives the Chebyshev Lobatto points. Useful for pseudospectral ...

### Legendre-Gauss Quadrature Weights and Nodes

... simple script which produces the Legendre-Gauss weights and nodes for computing the definite integral ... Users are encouraged to improve and redistribute this script. See also the script Chebyshev-Gauss-Lobatto quadrature ...

### Fast Chebyshev Differentiation

... is the Chebyshev collocation matrix, but much faster for large vectors x. Demands ... MATLAB Release: R14 ...
