How to loop through and create an nx2 vector?

Hi there,

I have a function 'myfunction' that takes a single number as an input and returns a 1x2 vector. How do I perform a loop such that I can create an nx2 vector for multiple input values. I'm trying this but seem to be doing something wrong.

for i = 1:n

output(i) = [myfunction(i)];

end

thanks!

Try

    output = nan( 10, 2 );
    for ii = 1:10
        output(ii,:) = myfunction(ii);
    end
