Numerical study of variational problems of moving or fixed boundary conditions by Muntz wavelets

Abstract: In this study, an approximation method with an integral operational matrix based on the Muntz wavelets basis is presented to solve the variational problems of moving or fixed boundary conditions and a computational algorithm is given for the suggested approach. First, the integral operational matrix is created through the Muntz wavelets. Then, by using this integral operational matrix with Lagrange multipliers, the present approach reduces the variational problem into the system of algebraic equations. This ap… Show more

“…In the work that is presented in [7], the direct method of differential transform method was employed for solving certain problems in the calculus of variations. The authors of [8] solved the variational problems of fixed or moving boundary conditions by an approximation method based on the operational matrix of integration for Muntz wavelets. An iterative technique for the approximate solution is applied to the calculus of variation in [9].…”
