Error in Matlab: Subscripted assignment dimension mismatch

Question

I have this problem and can't figure out what the problem is.

for i=1:e
    s  = size(E_{i});
    r2 = s(1);
    E_{i}(1:r2,3) = (E_{i}(:,2))/(E_{i}(:,1));
end

Subscripted assignment dimension mismatch.

Answer 1

You are using /, which is matrix division. Try using ./ (element-wise division), so that you get as many output elements as there are in input operands.

Answer 2

Have you tried looking at what size "(E_{i}(:,2))/(E_{i}(:,1));" is? Hint: you probably meant to use ./ instead of /.
