'for loop' trouble

basically i have two lists of doubles, each a single column, one longer than the other. every number in A is located somewhere in B, I just need to find where. So I tried to use a for loop, but ran into an issue.
A = [12; 15; 16; 19; 20];
B = [10; 11; 12; 13; 14; 15; 16; 17; 18; 19; 20];
My code is as follows:
for j=1:length(A)
ind = find(A==B)
end
the output basically keeps replacing 'ind' with a new value, when in fact i need to store all values of 'ind' that it generates. might be a simple fix but im still learning. thanks in advance

As with your question earlier, good job writing questions that are easy for us to understand and answer!

[junk,idx] = ismember(A,B)
idx is the location you're looking for.
(and to fix your for-loop)
for ii = length(A):-1:1
ind(ii) = find(A(ii)==B);
end
