I have multiple files of the same length that represent a and b. For each value in a, I need to create a table such that I get a1b1, a1b2, a1b3...to a1b10. Then a2b1, a2b2, a2b3....a2b10. Then a3b1, a3b2, a3b3....a3b10. This should happen until I get a10b1, a10b2, a10b3....a10b10. How would I create this loop?

As Rik suggested:
av = a(:);
bv = b(:);
[X,Y] = ndgrid(1:10);
M = [av(X(:)),bv(Y(:))]

yes, thanks a bunch. This got me going. I changed ndgrid to meshgrid and that produced the output I was looking for.

I personally prefer ndgrid, as the extension to higher dimensions is more obvious.
