Abstract:

In order to obtain a numerical solution for nonlinear Volterra-Fredholm-Hammerstein integral equation,the nonlinear Volterra-Fredholm-Hammerstein integral equations are transformed into a nonlinear system of algebraic equations by using BPFs as basis functionand combined with its orthogonally properties,and numerical solution of the original equation are obtained after discreting type of unknown variables. The numerical results show that the method is feasible and effective.

Key words: Block Pulse functions; nonlinear Volterra-Fredholm-Hammerstein integral equation; nonlinear algebraic equations; numerical solution
