Pseudospectral method for quadrilaterals

Journal of Computational and Applied Mathematics, 2011
In this paper, we investigate the pseudospectral method on quadrilaterals. Some results on Legendre–Gauss-type interpolation are established, which play important roles in the pseudospectral method for partial differential equations defined on ...
