colcompr          Scilab Group          Scilab Function            colcompr
NAME
   colcompr - column compression of polynomial matrix
  
CALLING SEQUENCE
 [Y,rk,ac]=colcompr(A);
PARAMETERS
 A    : polynomial matrix
      
 Y    : square polynomial matrix (right unimodular basis)
      
 rk   : normal rank of A
      
 Ac   : Ac=A*Y, polynomial matrix
      
DESCRIPTION
   column compression of polynomial matrix A (compression to the left)
  
EXAMPLE
 s=poly(0,'s');
 p=[s;s*(s+1)^2;2*s^2+s^3];
 [Y,rk,ac]=colcompr(p*p');
 p*p'*Y
