Create array of values returned from inside an if statement.

Here is sample code for what I am trying to achieve. This loop correctly returns the values I want (where the value is larger than the previous and subsequent values). Thus, it returns 4, 5, and 9 correctly. However, I want ex_vals to be an array of these values (ex_vals = [4,5,9]) but this code just returns and overwrites ex_vals each time. This seems simple but I have not used Matlab in a while. Any help is appreciated.

ex = [1,2,3,4,3,4,5,4,5,6,7,8,9,7];

for i = 2:length(ex)-1

if ex(i) > ex(i-1) & ex(i) > ex(i+1)

ex_vals = ex(i)

end

end

Subscript it —

ex = [1,2,3,4,3,4,5,4,5,6,7,8,9,7];
for i = 2:length(ex)-1
    if ex(i) > ex(i-1) & ex(i) > ex(i+1)
        ex_vals(i) = ex(i);
    end
end

ex_vals

ex_vals = 1×13

0 0 0 4 0 0 5 0 0 0 0 0 9
