sf2csf(T, Z)
Convert real Schur form to complex Schur form.
SciPy Reference Guide, Release 0.8.dev
Convert a quasi-diagonal real-valued Schur form to the upper triangular complex-valued Schur form.

Parameters
T : array, shape (M, M)
Real Schur form of the original matrix
Z : array, shape (M, M)
Schur transformation matrix
Returns
T : array, shape (M, M)
Complex Schur form of the original matrix
Z : array, shape (M, M)
Schur transformation matrix corresponding to the complex form
schur
Schur decompose a matrix
hessenberg(a, calc_q=0, overwrite_a=0)
Compute Hessenberg form of a matrix.
The Hessenberg decomposition is
A = Q H Q^H
where Q is unitary/orthogonal and H has only zero elements below the first subdiagonal.
Parameters
a : array, shape (M,M)
Matrix to bring into Hessenberg form
calc_q : boolean
Whether to compute the transformation matrix
overwrite_a : boolean
Whether to ovewrite data in a (may improve performance)
Returns
H : array, shape (M,M)
Hessenberg form of A
(If calc_q == True) :
Q : array, shape (M,M)
Unitary/orthogonal similarity transformation matrix s.t. A = Q H Q^H
