gcd(8)

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
