hermit

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 = %s;
p = [s, s*(s+1)^2, 2*s^2+s^3];
[Ar,U] = hermit(p'*p);
clean(p'*p*U)
det(U)

--> clean(p'*p*U)
 ans  =
  0  0  s²         

  0  0  s² +2s³ +s⁴

  0  0  2s³ +s⁴    

--> det(U)
 ans  =
  1
