Abstract: (6346 Views)
Hybrid of rationalized Haar functions are developed to approximate the solution of the differential equations. The properties of hybrid functions which are the combinations of block-pulse functions and rationalized Haar functions are first presented. These properties together with the Newton-Cotes nodes are then utilized to reduce the differential equations to the solution of algebraic equations. The method is computationally attractive, and applications are demonstrated through illustrative examples.
Keywords: Hybrid, Rationalized Haar functions, Block-pulse functions, Newton-Cotes, Differential equations, Nonlinear, Operational matrix, Orthogonal functions
