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

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)
det(U)
