Calculate the distance squared of a point in 3d space

how do I calculate the squared distance between two points in 3d space where the 2 inputs say P and Q and 1d arrays say P=[P1,P2,P3] and Q=[Q1,Q2,Q3]
so far i have the following but i don't think thats correct but I think im on the right track.
function [distanceSquared] = PixelDistance(P,Q)
P=[P1,P2,P3]
Q=[Q1,Q2,Q3]
distanceSquared =(P1-Q1).^2 +(P2-Q2).^2 +(P3-Q3).^2
end
thanks

function [distanceSquared] = PixelDistance(P,Q)
P1 = P(1); P2 = P(2); P3 = P(3);
Q1 = Q(1); Q2 = Q(2); Q3 = Q(3);
distanceSquared =(P1-Q1).^2 +(P2-Q2).^2 +(P3-Q3).^2
end
