mindspore.ops.BesselY0
- class mindspore.ops.BesselY0[source]
Computes Bessel function of the second kind, order 0 element-wise.
The formula is defined as:
\[\begin{split}\begin{array}{ll} \\ Y_{0}(x)=\lim_{n \to 0} \frac{J_{n}(x) \cos n \pi-J_{-n}(x)}{\sin n \pi} \end{array}\end{split}\]where \(J_{0}\) is Bessel function of the first kind, order 0.

Examples
>>> import mindspore >>> import numpy as np >>> from mindspore import Tensor, ops >>> bessel_y0 = ops.BesselY0() >>> x = Tensor(np.array([0.5, 1., 2., 4.]), mindspore.float32) >>> output = bessel_y0(x) >>> print(output) [-0.44451873 0.08825696 0.51037567 -0.01694074]
