A Direct Prediction of the Shape Parameter in the Collocation Method of Solving Poisson Equation
Mathematics, 2022 In this paper, we totally discard the traditional trial-and-error algorithms of choosing the acceptable shape parameter c in the multiquadrics −c2+∥x∥2 when dealing with differential equations, for example, the Poisson equation, with the RBF collocation ...
