Arranging values in an array
3 views (last 30 days)

I have some values in an array that I need to organize in ranges. lets say I am given different ages of people and I want to arrange them by their age group.
0-10, 11-20, 21-30, 31-40 I have been working on some code but I am uncertain how to finish it. Here is my code. Even just printing how many are in each range is fine with me.
Any help is greatly appreciated!
x = [3, 4, 8, 9, 9, 12, 12, 14, 14, 15, 17, 19, 21, 21, 22, 25, 27, 31, 32, 35, 35, 38];
for i = 1:size(x,1);
if(x <= 10);
elseif(x >=11)&(x <=20);
elseif(x >= 21)&(x <=30);
elseif(x >=31);
else
fprintf 'No values match your conditions\n'
end
end

You can do what you tried if you want to execute some code depending on the value. Or you can use histc(), if that's what you mean by organize.
x = [3, 4, 8, 9, 9, 12, 12, 14, 14, 15, 17, 19, 21, 21, 22, 25, 27, 31, 32, 35, 35, 38]
ranges = [0,11,21,31,41]
counts = histc(x, ranges)
In the command window:
x =
Columns 1 through 14
3 4 8 9 9 12 12 14 14 15 17 19 21 21
Columns 15 through 22
22 25 27 31 32 35 35 38
ranges =
0 11 21 31 41
counts =
5 7 5 5 0
