unzip the folder 'mk'and run test1.m which clusters random sample od 10,000 two dimension data into 5 clusters by K emans algorithm.
*************
clear;
clc;
% x is the vector of centroids of the cluser gropr. x(1),x(2) coordinates
% of first cluster and so on.so if no of clusters id k the dimension of x
% is 2*k
data=rand(10000,2);
% random data to be grouped as clusters
k=5;
save data
save k
options = gaoptimset('PopulationSize', 50,'Generations', 500,'StallGenLimit',500,'TimeLimit', 2000,'StallTimeLimit', 2000,'PlotFcns', {@gaplotbestf,@gaplotbestindiv});
[x F]=ga(@clust1,2*k,options)
% x=rand(1,10);
[F s1]=clust1(x);

plot(x1,y1,'*',x2,y2,'+ ',x3,y3,'s ',x4,y4,'. ',x5,y5,'v ');
hold on
plot(cx1,cy1,'kd');
% each cluster is chown is different colors and symbols, the centroids are pointed as dimond

can this algorithm use for my own data such as i want to use for breast cancer data

Great job. Thanks.
