findiff的Python项目详细描述
一个python包，用于任意维的有限差分导数。
Features:
- Differentiate arrays of any number of dimensions along any axis
- Partial derivatives of any desired order
- Accuracy order can be specified
- Accurate treatment of grid boundary
- Includes standard operators from vector calculus like gradient, divergence and curl
- Can handle uniform and non-uniform grids
- Can handle arbitrary linear combinations of derivatives with constant and variable coefficients
- Fully vectorized for speed
- Calculate raw finite difference coefficients for any order and accuracy for uniform and non-uniform grids
