             Fix For: 0.1.0


I propose a submatrix method as describe below.

  /**
   * Returns the sub-matrix of matrix
   * 
   * @param i0 the start index of row
   * @param i1 the end index of row
   * @param j0 the start index of column
   * @param j1 the end index of column
   * @return the sub-matrix of matrix
   * @throws IOException
   */
  public Matrix subMatrix(int i0, int i1, int j0, int j1) throws IOException;
