The paper presents a method for interpolation between given data points in n-dimensional space. Given the values and partial derivatives of a function for a set of points on an n-dimensional grid, an interpolation formula can be constructed which is exact for the values and partial derivatives at the given points. When the partial derivatives are not known, they can be approximated by the spline fit method which is described in Appendix A. Author
