public double determinant(double[][] M) {
  // System.out.println ("========");
  // print (M);
  if (!isSquare(M))
    throw new ArithmeticException("Trying to compute determinat on non-square matrix; aborted");
  if (M.length == 1) {
    return M[0][0];
  }
  if (M.length == 2) {
    return (M[0][0] * M[1][1]) - (M[0][1] * M[1][0]);
  }
  double sum = 0.0;
  for (int i = 0; i < M[0].length; i++) {
    sum += sign(i) * M[0][i] * determinant(subMatrix(M, 0, i));
  }
  return sum;
}
