pyFDN.fdn_matrix_gallery

pyFDN.fdn_matrix_gallery(N=None, matrix_type=None)

Return a feedback matrix of the requested type, or list all type names.

Parameters:

• N (int | None) – Matrix size. Ignored when matrix_type is None.

• matrix_type (str | None) – One of the supported type strings. Pass None (or call with no arguments) to get the list of all type names.

Return type:

ndarray | list[str]

Returns:

Feedback matrix of shape (N, N), or a list of type-name strings.

Example:

fdn_matrix_gallery()             # → list of type strings
fdn_matrix_gallery(4, "orthogonal")
fdn_matrix_gallery(8, "Hadamard")
