A Hard Clustering Algorithm Implemented in C++

class hcm

Save input data(to be custered) in a file accessible to the program Input file should contain:

firstline : data_column_count <space> clusters_to_be_formed_count
next lines : data rows each with data_column_count values

Usage

int main(int argc, char *argv[])
{
  ofstream out("test2.txt");
  ifstream in("input.txt");
  int data_count, cluster_count;
  in>>data_attr_count;
  in>>cluster_count;
  hcm test(cluster_count, data_attr_count, out);
  test.read_data(in);
  test.process();
  test.print_matrix();
  out.close();
  return 0;
