Name
hrmt — gcd of polynomials
Calling Sequence
[pg,U]=hrmt(v)
Parameters
- v
row of polynomials i.e. 1xk polynomial matrix
- pg
polynomial
- U
unimodular matrix polynomial
Description
[pg,U]=hrmt(v) returns a unimodular matrix U and pg = gcd of row of
polynomials v such that v*U = [pg,0].
Examples
x=poly(0,'x');
v=[x*(x+1),x^2*(x+1),(x-2)*(x+1),(3*x^2+2)*(x+1)];
[pg,U]=hrmt(v);U=clean(U)
