storing values of for loop in a matrix

Hi, i have a basic problem. i am using nested for loops x and y and calculating variable z. the variable z is over written at each iteration. at the end of loops, i want to have the variable z matrix. The x is 1xm vector, and y=1xn vector, how would i get the data matrix for z, where z=mxn. i use a simple test code below. Many thanks for any help

x=-60:0.5:-50;
y=-10:0.5:-5;
z=[];
for i=1:length(x)
    for j=1:length(y)
        z=x(i)+y(j)
    end
end

x = -60:0.5:-50;
y = -10:0.5:-5;
z = nan(numel(x),numel(y)); % better to preallocate array.
for i = 1:numel(x)
    for j = 1:numel(y)
        z(i,j) = x(i)+y(j); % indexing to allocate value to z.
    end
end
