Indexing a Matrix with a for loop

I have a matrix of complex numbers, z: z = [1+j 2+j 5+j;4+3j 6+2j 1+3j], and am trying to replicate z into y using a for loop. I thus have y = zeros(size(z));

My problem is that I do not know what to set i equal to in the for loop.

For example,

if I use

for i = size(z)
    y(i) = z(i)
end,

i is only covering the output of the size. How can I make it such that i will include every matrix index?

for ii = 1:numel(z) % don't name variables i or j (because they are interpreted as imaginary numbers by default)
