gcd              Scilab Group              Scilab Function              gcd
NAME
   gcd - gcd calculation
  
CALLING SEQUENCE
 [pgcd,U]=gcd(p)
PARAMETERS
 p    : polynomial row vector p=[p1,..,pn]
      
DESCRIPTION
   computes the gcd  of components of p and a unimodular  matrix (with
  polynomial inverse) U, with minimal degree such that
  
   p*U=[0 ... 0 pgcd]
  
EXAMPLE
 s=poly(0,'s');
 p=[s,s*(s+1)^2,2*s^2+s^3];
 [pgcd,u]=gcd(p);
 p*u
