hermit

Hermite form

Calling Sequence

[Ar,U]=hermit(A)

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)
