mindspore.ops.bessel_y1
- mindspore.ops.bessel_y1(x)[source]
Computes Bessel function of the second kind, order 1 element-wise.
The formula is defined as:
\[\begin{split}\begin{array}{ll} \\ Y_{1}(x)=\lim_{n \to 1} \frac{J_{n}(x) \cos n \pi-J_{-n}(x)}{\sin n \pi} \end{array}\end{split}\]where \(J_{1}\) is Bessel function of the first kind, order 1.
- Parameters
x (Tensor) – The input tensor. The data type must be float16, float32 or float64.
- Returns
Tensor, has the same shape and dtype as the x.
- Raises
- Supported Platforms:
GPU
CPU
Examples
>>> import mindspore >>> import numpy as np >>> from mindspore import Tensor, ops >>> x = Tensor(np.array([0.5, 1., 2., 4.]), mindspore.float32) >>> output = ops.bessel_y1(x) >>> print(output) [-1.47147239 -0.78121282 -0.10703243 0.39792571]
