• 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
