pyFDN.matrix_polyder# pyFDN.matrix_polyder(B, A)[source]# Derivative of rational filter matrices in the z^{-1} convention. Coefficients are ordered as [z^0, z^{-1}, z^{-2}, …] along axis 0. Parameters: B (ndarray) – Numerator coefficients, shape (order, N, M). A (ndarray) – Denominator coefficients, shape (order, N, M). Returns: Numerator of the derivative, shape (order, N, M). P: Denominator of the derivative, shape (order, N, M). Return type: Q
