function h = histp(x, xmin, xmax, nbins)%HISTP Histogram estimate of 1-dimensional probability distribution.%% Description%% HISTP(X, XMIN, XMAX, NBINS) takes a column vector X of data values% and generates a normalized histogram plot of the distribution. The% histogram has NBINS bins lying in the range XMIN to XMAX.%% H = HISTP(...) returns a vector of patch handles.%% See also% DEMGAUSS%% Copyright (c) Ian T Nabney (1996-2001)ndata = length(x);bins = linspace(xmin, xmax, nbins);binwidth = (xmax - xmin)/nbins;num = hist(x, bins);num = num/(ndata*binwidth);h = bar(bins, num, 0.6);
