expm_frechet_kronform(A, method=None, check_finite=True)

Notes

This function is used to help compute the condition number of the matrix exponential.

Parameters

A : array_like with shape (N, N)

Matrix to be expm'd.

method : str, optional

Extra keyword to be passed to expm_frechet.

check_finite : bool, optional

Whether to check that the input matrix contains 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

K : 2-D ndarray with shape (N*N, N*N)

Kronecker form of the Frechet derivative of the matrix exponential.

Construct the Kronecker form of the Frechet derivative of expm.

See Also

expm

Compute a matrix exponential.

expm_cond

Compute the relative condition number of the matrix exponential in the Frobenius norm.

expm_frechet

Compute the Frechet derivative of the matrix exponential.

Examples

See :

Local connectivity graph

Hover to see nodes names; edges to Self not shown, Caped at 50 nodes.

Using a canvas is more power efficient and can get hundred of nodes ; but does not allow hyperlinks; , arrows or text (beyond on hover)

SVG is more flexible but power hungry; and does not scale well to 50 + nodes.

All aboves nodes referred to, (or are referred from) current nodes; Edges from Self to other have been omitted (or all nodes would be connected to the central node "self" which is not useful). Nodes are colored by the library they belong to, and scaled with the number of references pointing them
