sqrt(sum((A1 ./ repmat(nanstd(A1), size(A1,1), 1) - A2 ./ repmat(nanstd(A2), size(A2,1), 1)).^2, 2))
This would be for taking the distance for the rows of A1 to the corresponding rows of A2.
I am thinking that possibly it should be different, like this:
sqrt(sum(((A1-A2) ./ repmat( nanstd([A1;A2]), size(A1,1), 1)).^2,2))
