mindspore.ops.Zeta

class mindspore.ops.Zeta

Compute the Hurwitz zeta function ζ(x,q) of input Tensor.

Warning

This is an experimental API that is subject to change or deletion.

$$\zeta (x,q)=\sum _{n=0}^{\mathrm{\infty }}{(q+n)}^{-x}$$

Warning

This is an experimental API that is subject to change or deletion.

Inputs:

• x (Tensor) - A Tensor, types: float32, float64.

• q (Tensor) - A Tensor, must have the same shape and type as x.

Outputs:

Tensor, has the same dtype and shape as the x.

Raises

• TypeError – If either of x and q is not tensor.

• TypeError – If dtype of x is neither float32 nor float64.

• TypeError – If dtype of q is neither float32 nor float64.

• ValueError – If shape of x is not same as the q.

Supported Platforms:

Ascend GPU CPU

Examples

>>> x = Tensor(np.array([10.]), mindspore.float32)
>>> q = Tensor(np.array([1.]), mindspore.float32)
>>> zeta = ops.Zeta()
>>> z = zeta(x, q)
>>> print(z)
