No, that code would calculate the distances over a grid of points, not over a list of points with specific locations. Also, that code will throw away the distances after it calculates them.
Suppose you have a vector of length 10 for latitudes, and another for longitudes. lats(1) corresponds to A's latitude, lats(2) for B's lat, longs(1) for A's long, and so on. Then
a5= 2.227804;
b5=103.35091;
for K = 1 : length(lats)
thislat = lats(K);
thislong = longs(K);
dDgree(K) = distance(thislat, thislong, a5, b5);
end
