# A multivariant interpolation routine for a random distribution of data points

## Description

Abstract We have developed a multivariant interpolation program which interpolates and calculates the derivatives of any function defined on a set of points randomly distributed in a three-dimensional space. Based on the Taylor expansion, the interpolation problem is transformed to find a solution of a linear equation. It is demonstrated that there is no restriction required on the data structure in the present routine and that an ill-condition problem is removed from the process when solving the line...
