Pseudospectral method for quadrilaterals
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
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
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 ...
