How do you save values from a for-loop in a vector?

I have the following:

for ml=100:50:1000 
    z=fzero(@(x) y(x,ml), [1 10]);
    disp(num2str(z))
end

But I need each value of z saved as a vector to use it in a plot later. How do you do that?

With MATLAB it is almost always better to loop over an index than to loop over data:

ml = 100:50:1000;
n = numel(ml);
z = nan(1,n); % preallocate
for k = 1:n % loop over indices
    z(k) = fzero(@(x) y(x,ml(k)), [1,10]);
end %^^^     indexing       ^^^
