The proposed approximation matrix allows an efficient computation of the action of the interpolation matrix, so it can be profitably used in the iterative solution of the interpolation system even if the original coefficient matrix is dense.

Abstract
The Taylor expansion is used to obtain an approximation of the inverse multiquadric radial basis function (IMRBF) interpolation matrix. The proposed approximation matrix allows an efficient computation of the action of the interpolation matrix, so it can be profitably used in the iterative solution of the interpolation system even if the original coefficient matrix is dense.File in questo prodotto:
