%% Specify Histogram Bin Intervals  

% Copyright 2015 The MathWorks, Inc.


%% 
% Plot three histograms of the same data using different bin intervals:
% 
% * In the upper subplot, specify the bin centers using a vector of evenly
% spaced values that span the values in |x|.
% * In the middle subplot, specify the bin centers using a vector of evenly
% spaced values that do not span the values in |x|. The first
% and last bins extend to cover the minimum and maximum values in |x|.
% * In the lower subplot, specify the bin intervals using a vector of unevenly
% spaced values. The |hist| function uses the midpoints between consecutive
% values as the bin edges and indicates the specified values by markers
% along the _x_-axis.
