findiff 0.6.2

A Python package for finite difference derivatives in any number of dimensions.

A Python package for finite difference derivatives in any number of dimensions.

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
