 Usage:  bd = chold(x,l)   

 

 Input:



  x                      n x n matrix, the input matrix 

                         

                         

  l                      scalar, the number of lower non-zero subdiagonals including 

                         

                         the diagonal, l<=dim(x) 

                         

                         

 Output:



  bd                     n x n matrix, see note
