✦ Synopsis

coordinate Multiquadric approximation scheme Numerical comparison of the solutions Condition number a b s t r a c t

This paper introduces a variant of direct and indirect radial basis function networks (DRBFNs and IRBFNs) for the numerical solution of Poisson's equation. We use transformation from Cartesian coordinates to polar ones and use DRBFN and IRBFN methods on the basis of a multiquadric approximation scheme. We have experienced that the result shows better accuracy than previously known ones. Also, our new way of solution does not influence the condition number.
