C = horzcat(A1, A2, ...) horizontally concatenates matrices A1, A2, and so on. All matrices in the argument list must have the same number of rows

... and if the vectors are not of the same lengths, you can use PADCAT

out=zeros(1000,2) % Pre-allocate
for k=1:1000
out(k,:)=... % your calculations
end
