hermit - Hermite form

### Calling Sequence

  `[Ar,U]=hermit(A)`

### Parameters

- `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)
