HessenbergDecomposition
 Usage
Notes
 Further Examples
This gives the Hessenberg decomposition of the matrix  as a unitary matrix  and an upper triangular matrix  with nonzero first subdiagonal.
In[1]:=
|
Out[1]=
|
This checks that the decomposition is correct.
In[2]:=
|
Out[2]=
|
This checks that the matrix  is unitary.
In[3]:=
|
Out[3]=
