The first four numbers of each data give the year. I want to bin the data according to their years. How should I do that? if the year is 2004 assign it to an array T1. if the year is 2005 assign it to an array T2. So on.

A = [ List of numbers ];
x = floor(A/1000);
T1 = A( x == 2004 );
T2 = ...

b=arrayfun(@num2str,a,'un',0)
c=cellfun(@(x) str2num(x(1:4)),b)
[ii,jj,kk]=unique(c)
idx=arrayfun(@(x) find(ismember(c,x)),ii,'un',0)
out=cellfun(@(x) a(x),idx,'un',0)
celldisp(out)
