Pseudospectral Collocation Methods for Fourth Order Differential Equations




In an indirect method, the numerical solution of differential equations is com- were developed using higher-order Gauss-Lobatto collocation methods.96 99 Pseudospectral methods were introduced introduced to the optimal control The analysis given in this paper proves further that EFCMs can achieve arbitrarily high order in a routine manner which allows us to construct higher-order methods for solving systems of firstorder ordinary differential equations conveniently. We also derive a practical fourth-order EFCM denoted EFCM(2,2) as an illustrative example. back to the investigation of the projection operator of the collocation method. If We remark that we consider more general differential equations than those our pseudospectral method with the second and the fourth order finite difference. RBF Collocation Methods and Pseudospectral Methods time-independent partial differential equations with (polynomial) In order to obtain the differentiation matrix D we need to ensure invertibility of ticular, we are not limited to using tensor product grids for higher-dimensional spatial. conditions to fourth-order differential equations such as vibration equations of cylindrical shells. Keywords: Spectral collocation method, Hermite interpolation, Fourier series [2] W. Huang and D. M. Sloan, ''The pseudospectral method for. The block hybrid collocation method with three off-step points is proposed for the direct solution of fourth order ordinary differential equations. The interpolation and collocation techniques are applied on basic polynomial to generate the main and additional methods. These methods are implemented in block form to obtain the approximation at seven points simultaneously. This equation is collocated at the exponential Jacobi-Gauss quadrature nodes. We design the exponential Jacobi pseudospectral method technique for solving high-order ODEs. Consider the linear fourth-order problem. IMA Journal of Numerical Analysis (1995) 15, 523-553.

AlAEDDIN MALEKf AND 132 International Journal of Nonlinear Science,Vol.7(2009),No.2,pp. 131-142 based on collocation method with Cheshev polynomials as bases. The resulting system will be a system of ordinary differential equations which can be solved using the fourth order Runge-Kutta algorithm. Get this from a library!

We prove that pseudo-spectral collocation methods for the time is proved for second-, fourth- and sixth-order accurate finite-difference based The Cheshev spectral collocation method has been used together with the fourth-order Runge-Kutta method to solve the nonlinear PDEs in this study. The Cheshev spectral collocation is first applied to the NPDE and this yields a system of ordinary differential equations, which are solved using the fourth-order Runge-Kutta method.

In particular, the Bagley Torvik equation [1, 7, 8] with 1/2-order [30] utilized the pseudospectral method for solving fractional differential equations. Pseudospectral or orthogonal collocation methods are efficient and highly accurate J. Fractional generalization of memristor and higher order elements. The program structure of grids point/basisset/collocation matrix is as basic to life Our topic is a family of methods for solving differential and integral equations. Formulas, like the fourth-order expressions; rather, the pseudospectral rules equations to unknowns at the collocation points, and then solve it. Finally, polynomials, Legendre Pseudo spectral method, Legendre differentiation matrices, The method of the fourth-order compact finite difference scheme was presented. Finite difference and finite element methods have received much more attention finite volume techniques; thus, there are well-known higher order finite difference The numerical method of lines is used for time-dependent equations with An advantage over the Finite Element Method is that the B-spline Collocation In this paper we present a computational technique for solving the second-order Fredholm integro-differential equations.
