An application of rationalized Haar functions for variational problems. (English) Zbl 1020.49026
Summary: A direct method for solving variational problems using rationalized Haar functions is presented. An operational matrix of integration and the cross product of two rationalized Haar function vectors are utilized to reduce a variational problem to the solution of algebraic equations. Illustrative examples are included to demonstrate the validity and applicability of the technique.
