• NUMERICAL INTEGRATION OVER AN ARBITRARY RECTANGLE AND SQUARE REGION USING GENERALISED GAUSSIAN QUADRATURE RULES
Abstract
We consider the problem of numerical integration of a arbitrary function over a rectangle and square region using transformation of variables new nodal points and its weight coefficients are estimated. The Generalised Gaussian quadrature over a rectangle and square domain integrals of any arbitrary functions is illustrated with some numerical examples.
