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

正在学数字信号处理,感觉上学期信号与系统学得不扎实，因为当时只是死记公式，这学期数信老师提倡动手实践，觉得自己在编程中对公式理解得更加深刻了。 以下是我写的FFT，欢迎指教。-is studying digital signal processing, signal feel semester with enough solid school system, because only memorizing formulas, a few letters this semester to promote hands-teachers find themselves in the right programming formula to understand more deeply. The following is what I wrote FFT welcome to enlighten.
