Using 'If statements' and 'for loops', my matrix isn't populating properly!

jumps = zeros(10,5);

for i = 1:10

 for j = 1:5

if top_currencies_vol_change(i,j) < 0.75

 jumps(i,j) =  -1;

return

else

if top_currencies_vol_change(i,j) > 1.25

 jumps(i,j) =  1;

return

end

end

end

end

Using the above code, the matrix populates until the first condition of one of the if statements is satisfied, e.g.

                                   0     0     0     0     0
                                   0     0     0     1     0
                                   0     0     0     0     0
                                   0     0     0     0     0
                                   0     0     0     0     0
                                   0     0     0     0     0
                                   0     0     0     0     0
                                   0     0     0     0     0
                                   0     0     0     0     0
                                   0     0     0     0     0

when I want it to continue populating until the entire matrix has been completed. Any idea why it just stops after the first success?

its because of the return command.

example

for i=1:10
   disp(i);
   return;
end

% correct version

for i=1:10
   disp(i);
end
