an application of hybrid of hartley functions for variational problems

a numerical method for solving variational problems is presented in this paper. the method is based upon hybrid of hartley functions approximations. the properties of hybrid functions which are the combinations of block-pulse functions and hartley functions are first presented. the operational matrix of integration is then utilized to reduce the variational problems to the solution of algebraic equations. illustrative examples are included to demonstrate the validity and applicability of the technique.
