How do I make my user defined function accept vectors as inputs rather than scalars?

Specifically I would like to make my input (d) a vector. How do I change my code so that my function accepts the vector as input?
function Fgravitational=GravForce(m1,m2,d)
%Newtons Gravitational force eqation
%inputs: mass 1, mass 2, distance
%output: force of gravity in N
G=6.672e-11;
Fgravitational=-G*((m1*m2)/d^2);
fprintf('The gravitational force is %.3e N \n ', Fgravitational);
end

Fgravitational=-G*((m1*m2)/d^2);
Put a . before the mathematical operators:
G.*((m1.*me)./d.^2)
There's a helper function vectorize that does this for you.
