hermit

hermit — Hermite form

Calling sequence

[Ar,U]=hermit(A)

`A`	: polynomial matrix
`Ar`	: triangular polynomial matrix
`U`	: unimodolar polynomial matrix

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



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