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)
