hermit

Arguments

A

polynomial matrix

Ar

triangular polynomial matrix

U

unimodolar polynomial matrix

Description

Hermite form: U is an unimodular matrix such that A*U is in Hermite triangular form:

The output variable is Ar=A*U.

Warning: Experimental version

Examples

s=poly(0,'s'); p=[s, s*(s+1)^2, 2*s^2+s^3]; [Ar,U]=hermit(p'*p); clean(p'*p*U), det(U)
