This package provide methods for calculating (usually)
accurate numerical first and second order derivatives. Accurate
calculations are done using Richardson's extrapolation or, when
applicable, a complex step derivative is available. A simple
difference method is also provided. Simple difference is
(usually) less accurate but is much quicker than Richardson's
extrapolation and provides a useful cross-check. Methods are
provided for real scalar and vector valued functions.
