AbstractWe propose a modified bivariate Shepard operator of least squares thin-plate spline type based on an iterative method, introduced by…

The strict superlinear order can be faster than the infinite order

3 years ago

Abstract The strict superlinear order (superlinear convergence) was usually regarded as having an intermediate speed between between linear and with…
