Spectral collocation methods [PDF]

open access: yesApplied Numerical Mathematics, 1989
This is a survey article on the application of spectral collocation methods to the solution of partial differential equations. For the most part, the basis functions used are either trigonometric or Chebyshev polynomials, although there is some discussion of Legendre polynomials.

A pk-Adaptive Mesh Refinement for Pseudospectral Method to Solve Optimal Control Problem

open access: yesIEEE Access, 2019
In this paper, a pk-adaptive mesh refinement of pseudospectral method is proposed for solving optimal control problem by using collocation at Legendre-Gauss-Lobatto (LGL) points, motivated by reducing the redundant collocation points in the state-of-art ...

Boundary element collocation methods using splines with multiple knots [PDF]

open access: yes, 1995
We extend the theory of boundary element collocation methods by allowing reduced inter-element smoothness (or in other words, by allowing trial functions that are splines with multiple knots).

Numerical Solution of Higher Index Nonlinear Integral Algebraic Equations of Hessenberg Type Using Discontinuous Collocation Methods

open access: yesMathematical Modelling and Analysis, 2014
In this paper, we deal with a system of linear and nonlinear integral algebraic equations (IAEs) of Hessenberg type. Convergence analysis of the discontinuous collocation methods is investigated for the large class of IAEs based on the new definitions ...
