The problem begins in this section of your code:

      % Direction analysis %
      if (end_col < p2)
          if ((M(p1, row) == 2)||(M(p1,row)==1))
              path_row(row_trace) = row;
              path_col(col_trace) = p1;
              found = 1;
          elseif((M(p2, row) == 2)||(M(p2,row)==1))
              path_row(row_trace) = row;
              path_col(col_trace) = p2;
              found = 1;
          elseif((M(p3, row) == 2)||(M(p3,row)==1))
              path_row(row_trace) = row;
              path_col(col_trace) = p3;
              found = 1;
          end
      end
      else
