mindspore.ops.zeta

mindspore.ops.zeta(input, other)

Elemental-wise compute the Hurwitz zeta output.

$$\zeta (x,q)=\sum _{k=0}^{\mathrm{\infty }}\frac{1}{(k+q{)}^x}$$

Warning

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

Parameters

• input (Union[Tensor, int, float]) – Input Tensor. Represented as $x$ in the formula. If it's a Tensor, its dtype must be either float32 or float64.

• other (Union[Tensor, int, float]) – Input Tensor must have the same dtype as input. Represented as $q$ in the formula.

Returns

Tensor, The result of Hurwitz zeta function.

Raises

• TypeError – If neither input nor other is not tensor.

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

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

Supported Platforms:

Ascend GPU CPU

Examples

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