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

Answer 1

[Sean de Wolski]

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.
