Modified Laguerre pseudospectral method refined by multidomain Legendre pseudospectral approximation

open access: yesJournal of Computational and Applied Mathematics, 2006
A modified Laguerre pseudospectral method is proposed for differential equations on the half-line. The numerical solutions are refined by multidomain Legendre pseudospectral approximation.

Pseudospectral method for quadrilaterals

open access: yesJournal 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 ...

A Pseudospectral Method for Hammerstein Equations

open access: yesJournal of Mathematical Analysis and Applications, 1996
This paper considers Hammerstein equations[formula]and presents a pseudospectral method for solving them numerically. The method is applied to approximate the solution not to the equation in its original form, but rather to an equivalent equationz(t)=g(t,

Direct trajectory optimization based on a mapped Chebyshev pseudospectral method

open access: yesChinese Journal of Aeronautics, 2013
In view of generating optimal trajectories of Bolza problems, standard Chebyshev pseudospectral (PS) method makes the points’ accumulation near the extremities and rarefaction of nodes close to the center of interval, which causes an ill-condition of ...

Optimal trajectory planning for trains – A pseudospectral method and a mixed integer linear programming approach

open access: yesTransportation Research Part C: Emerging Technologies, 2013
The optimal trajectory planning problem for train operations under constraints and fixed arrival time is considered. The varying line resistance, variable speed restrictions, and varying maximum traction force are included in the problem definition.
