 Usage:  y = grbiplot(x,r,k)  

 

 Input:



  x                      n x p matrix (n >= p) (n cases, p variables) 

                         

  r                      number, rank of approximation (d <= p) 

                         

  k                      number, 0 <= k <= 1 

                         

 Output:



  b                      n+p x d matrix, containing the coordinates for the 

                         biplot
