A package collecting utilities and other convenient functionality for various numerical computations:
- Numerical differentiation: based on finite differences.
- Interpolation: provide a common interface for several useful interpolators from the excellent 'splines' and 'scipy.interpolate' packages.
- Numerical optimization: transformation functions to impose constraints using unconstrained optimization algorithms.
- Fast or robust python implementations of certain matrix operations.
- Sorting, timing, and other utilities.
