in this code
figure('Color', 'white')
dis = zeros(50,8);
UserLocationX = randi(50, 1, 50);
UserLocationY = randi(50, 1, 50);
AccessPointX = randi(50, 1, 8);
AccessPointY = randi(50, 1, 8);
for k=1:50
for l=1:8
dis (k,l)= sqrt((UserLocationX(k)-AccessPointX(l)).^2 + (UserLocationY(k)-AccessPointY(l)).^2);
end
end
plot(dis,'d'), grid on
xlabel('x1')
ylabel('y1')

This will calculate the minimum distance from each user to an access point. The C is the distance for that particular user (row number in this instance), and I is the index of that distance (column number), corresponding to the number of the access point:
[C,I] = min(dis,[],2)
