Description:
Steps to reproduce:

- Reverse Engineer  'RectangularMatrix getCopy()' method from
'RectangularMatrix' class
  and create a Sequence diagram:

  ---------------------------------------------------------------
  public class RectangularMatrix {
    
    protected final int dimN;
    protected final int dimM;
    
    protected final double element[][];
    
    public RectangularMatrix(int dimN, int dimM) {
        this.dimN = dimN;
        this.dimM = dimM;
        element = new double[ this.dimN ][ this.dimM ];
    }
    
    public RectangularMatrix getCopy() {
        
        RectangularMatrix copy = new RectangularMatrix(dimN, dimM);
        
        for(int i=0; i< dimN;  i++){
            for(int j=0; i< dimM;  j++){
                copy.element[i][j] = element[i][j];
            }
        }
        
        return copy;
    }
  }
  ---------------------------------------------------------------

  There are 'element:double' and 'element[]:double' Lifelines 
    on the Sequence diagram which are not used within the method.
