hrmt

Arguments

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)
det(U)
