If and & conditions together

Question

How can I properly formulate the following if.

I want to compare each element of 2 vectors [x1_grid and x2_grid] with the same size (1x671) .

If x1_grid(1) < x2_grid(1) & x1_grid(2) < x2_grid(2) & .... x1_grid(end) < x2_grid(end)

Then I want to write a vector [x1_is_less =1] but if only one of the and's is not holding then I want to write [x1_is_less =0]

This is my code, but something is not really working as I want, I guess my problem is to introduce the "and" condition within the loop.

can someone help me?

Thanks in advance!

for    i = 1 : length(x1_grid)
        if x1_grid(i) < x2_grid(i)
        x1_is_less = 1;
        else
        x1_is_less = 0;
        end
end

x1_is_less = all(x1_grd < x2_grid);
