%description
Discretely-sampled function is first smoothed.  Features of the smoothed
function are then extracted.  Some of the key features include mean value,
first and second derivatives, critical points (i.e. local maxima and
minima), curvature of cunction at critical points, wiggliness of the
function, noise in data, and outliers in data.
