ABSTI~ACT : This paper establishes a clear procedure for the variational problem solution via the Walsh functions technique. First the Walsh functions are introduced and their properties briefly summarized. Then an operational matrix is derived for integration use. The variational problems are solve

β¦ Synopsis
A direct methodfor solving variationaIproblems using Taylor series is discussed. Properties of' Taylor series are brieJy presented and an operational matrix is utilized to solve the variational problems by means of a direct method. An illustrative example is given.

A parameter-free variational iterative method is proposed for scattering problems. The present method yields results that are far better, in convergence, stability and precision, than any other momentum space method. Accurate result is obtained for the atomic exponential (Yukawa) potential with an e
