The Construction Of Some Optimal 2D Cubature Formulae

&
Pages 1233-1242 | Published online: 15 Sep 2010
 

In this paper, we showcase some formulae that have been derived using the least squares optimisation method, which produces cubatures that are superior for use with singular integrals. We consider some formulae of standard and well-known structure for two differing weight functions, (i) w(x, y)=1 and (ii) w(x, y)= \sqrt{x^2 + y^2} .
