Publisher review:Inverse (integrated) gradient - Vectorized & fully sparse 1-d, 2-d, & 3-d integrated gradients The inverse of the gradient function. I've provided versions that work on 1-d vectors, or 2-d or 3-d arrays. In the 1-d case I offer 5 different methods, from cumtrapz, and an integrated cubic spline, plus several finite difference methods.In higher dimensions, only a finite difference/linear algebra solution is provided, but it is fully vectorized and fully sparse in its approach. In 2-d and 3-d, if the gradients are inconsistent, then a least squares solution is generated.(I'll enhance the 2-d and 3d tools if there is any interest. Currently they are set to be 2nd order methods on uniform grids.) Requirements: ยท MATLAB Release: R14SP1
Inverse (integrated) gradient is a Matlab script for Mathematics scripts design by John D`Errico.
It runs on following operating system: Windows / Linux / Mac OS / BSD / Solaris.
