REDUCED ROW ECHELON

\(The\ \ 4 x3\ matrix\ A\ is\ specified\ by\ giving\ a\ list\ of\ 4\ 
        elements, \ where\ each\ element\ lists\ the\ entries

      in\ a\ row\ of\ A . \ For\ example, \ 
      the\ first\ row\ of\ A\ has\ entries\ 1, 6, 3, \ 
      etc . 
Then\ the\ reduced\ row\ echelon\ form\ of\ A\ is\ 
        \(found . \)\)

\(A = {{1, 6, \ 3}, {1, 4, 2}, \ {1, 3, 1}, {2, 4, 6}};
