solving simple equations in matlab

I have 2 variables:
d1 = 1:5;
d2 = 6:10;
I would like to calculate 'dat', which is given by:
dat = d1./(10.*d2);
However, the following returns a vector (as expected), how would I write this so that matlab returns a matrix i.e. the value for dat when d1 is 1:5 when d2 is 6 and then when d2 is 7, ultimately returning a 5x5 matrix. Is the only method of completing this through a loop.

dat = d1.'*(.1./d2);

dat = bsxfun(@rdivide, d1.', d2) ./ 10;

d1 = 1:5;
d2 = 6:10;
for j=1:5
dat(j,:) = d1./(10.*d2(j));
end
dat
