scipy.linalg.rsf2csf

scipy.linalg.rsf2csf(T, Z, check_finite=True)

Convert real Schur form to complex Schur form.

Convert a quasi-diagonal real-valued Schur form to the upper triangular complex-valued Schur form.

Parameters:

T : (M, M) array_like

Real Schur form of the original matrix

Z : (M, M) array_like

Schur transformation matrix

check_finite : bool, optional

Whether to check that the input matrices contain only finite numbers. Disabling may give a performance gain, but may result in problems (crashes, non-termination) if the inputs do contain infinities or NaNs.

Returns:

T : (M, M) ndarray

Complex Schur form of the original matrix

Z : (M, M) ndarray

Schur transformation matrix corresponding to the complex form
