How to Save the outputs of my for loop?

I have this code:

x=1:10;
for i=1:length(x);
    y=rand(i)
end

which is doing what I want to, but it's not saving the answers in my workspace, so I tried this:

x=1:10;
for i=1:length(x);
    y(i)=rand(i)
end 

 But that comes out with an error that says, "In an assignment  A(:) = B, the number of elements in A and B must be the same."

Thanks for the help..

rand(i) is going to create a different sized matrix for each iteration, namely a square matrix of size i x i. That's why you are getting the error. If this is really what you want, then you can use cell arrays. E.g.,

y{i} = rand(i);

If you are just trying to generate a single random number for each iteration, then

y(i) = rand;

Or in the latter case you could just get rid of the loop entirely with:

y = rand(size(x));
