摘要:High-order implicit explicit Runge--Kutta schemes are introduced with the attention on the implementation for problems with nonhomogeneous boundary conditions. Also, the multi-interval Legendre tau methods are developed for solving ordinary differential equations with the collocation treatment of the nonlinear term. Optimal error estimate is derived.  The method is then applied to the time discretization of spectral methods for some nonlinear partial differential equations. Numerical examples are given for comparison.
