X3=[-6.189; -3.251; 2.926; 6.534; 10.79; 5.203; -4.465; 1.42; -8.66; -0.8748; 6.534 ; 11.251] ;
Y3=[ 1.393; 10.42; 6.639; 5.821; 8.425; 2.924; 1.139; 0.7508; -7.917; -6.928; -10.01; -7.03; 5.639];
X3 and Y3 are my corrdinates of data.
I want 4 clusters whose centroid would be (x_b,y_b)
x_b=[0.7298; 3; -5.23; 11.86];
y_b=[12.48; -1.497; -6.139; -3.23];
how can i do this..?

Y3=[ 1.393; 10.42; 6.639; 5.821; 8.425; 2.924; 1.139; 0.7508; -7.917; -6.928; -10.01; -7.03; ];
x_b=[0.7298; 3; -5.23; 11.86];
y_b=[12.48; -1.497; -6.139; -3.23];
P = [X3 Y3] ; % points
G = 4 ; % number of groups
C = [x_b y_b] ; % centroids
idx = kmeans(P,G,'MaxIter',10,'Start',C);
gscatter(P(:,1),P(:,2),idx)
