A method for calculating meshless finite difference weights
An exact method for calculating the finite difference weights for arbitrary distributed points in multiple dimensions is presented. The method avoids the numerical ill conditioning associated with a small-scale factor () by delaying the limiting of 0. The Gaussian Radial Basis function is approximated by a Taylor's series expansion in the variable , and the resultant matrix equation is solved using the Fraction Free LU decomposition method.
