NAME
   lcmdiag - least common multiple diagonal factorization
  
CALLING SEQUENCE
 [N,D]=lcmdiag(H)
 [N,D]=lcmdiag(H,flag)
PARAMETERS
 H    : rational matrix
      
 N    : polynomial matrix
      
 D    : diagonal polynomial matrix
      
 flag : character string: 'row' or 'col'\fr (default)
      
DESCRIPTION
   [N,D]=lcmdiag(H,'row') computes a factorization D*H=N, i.e.  H=D^(-1)*N 
  where D is a diagonal matrix with D(k,k)=lcm of  kth row of H('den').
  
   [N,D]=lcmdiag(H) or [N,D]=lcmdiag(H,'col) returns H=N*D^(-1) with
  diagonal D and D(k,k)=lcm of kth col of H('den')
  
EXAMPLE
 s=poly(0,'s');
 H=[1/s,(s+2)/s/(s+1)^2;1/(s^2*(s+2)),2/(s+2)];
 [N,D]=lcmdiag(H);
 N/D-H
