pymiediff.special.f_der

pymiediff.special.f_der(n: Tensor, z: Tensor, f_n: Tensor, **kwargs)

Differentiate order-indexed spherical Bessel-like sequences.

Parameters:

• n (int or torch.Tensor) – Maximum order.

• z (torch.Tensor) – Argument values.

• f_n (torch.Tensor) – Sequence values for orders 0..n along axis 0.

Returns:

Derivative values with same shape as f_n.

Return type:

torch.Tensor
