MATLAB: Cumulative sum in matrix

matrix

How do i generate a 5×10 matrix such as:

       Z1       Z2       Z3   ...  Z4 Z5 Z6 Z7 Z8 Z9 Z10 ( each Z is a random number)
       Z1+Z1'   Z2+Z2'   Z3+Z3'      ( cumulative sum of previous Z value with Z', Z' is a new random number)      
     .
     .
    Z1+Z1'+Z1''+Z1'''+Z1''''

MATLAB: Cumulative sum in a loop

Z = rand(10,1,10);
Z_add = randi(5,2,10);
out = cumsum([Z;Z_add]);

with for - loop

m = 5;
Z = randi(20,1,10);
n = size(Z,2);
Z_out = [Z;zeros(m-1,n)];
for ii = 2:m
    Z_out(ii,:) = Z_out(ii-1,:) + randi(5,1,n);
end
