    %% Return Bin Numbers for Histogram 
% Defined |ages| as a vector of ages. Sort |ages| into bins with
% varying ranges between 0 and 75.

ages = [3,12,24,15,5,74,23,54,31,23,64,75];
binranges = [0,10,25,50,75];

[bincounts,ind] = histc(ages,binranges)

%%
% |bincounts| contains the number of values in each bin. |ind| indicates
% the bin numbers.
