%% Create Histogram Plot % Initialize the random number generator to make the output of |randn| % repeatable. % Copyright 2015 The MathWorks, Inc. rng(0,'twister') %% % Define |x| as 100 normally distributed random numbers. Define % bin ranges between -4 and 4. Determine the number of % values in |x| that are within each specified bin range. Return the number % of elements in each bin in |bincounts|. x = randn(100,1); binranges = -4:4; [bincounts] = histc(x,binranges) %% % To plot the histogram, use the |bar| function. figure bar(binranges,bincounts,'histc')
