wolffd@0: %	Description
wolffd@0: %
wolffd@0: %	HISTP(X, XMIN, XMAX, NBINS) takes a column vector X  of data values
wolffd@0: %	and generates a normalized histogram plot of the  distribution. The
wolffd@0: %	histogram has NBINS bins lying in the range XMIN to XMAX.
wolffd@0: %
wolffd@0: %	H = HISTP(...) returns a vector of patch handles.
