Did you try this:
distances = sqrt((xp - xyz(:,1))^2 + (yp - xyz(:,2))^2 + (zp - xyz(:,3))^2);
sumOfDistances = sum(distances);
[minDistance, indexOfMin] = min(distances);
where (xp, yp, zp) is the single point, and xyz is the array of all points?

So put it inside a loop over p and do that code for every point p. Why can't you do that?
