Name
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)
