mindspore.ops.bessel_j1

mindspore.ops.bessel_j1(x)

Computes the first order Bessel function of the first kind for each element input.

$$\begin{array}{r}\begin{array}{l}\\ J_1(x)=\frac{1}{\pi }{\int }_0^{\pi }\cos (x\sin \theta -\theta )d\theta =\sum _{m=0}^{\mathrm{\infty }}\frac{(-1{)}^m{x}^{2m+1}}{2^{2m+1}m!(m+1)!}\end{array}\end{array}$$

Parameters

x (Tensor) – The input tensor.

Returns

Tensor

Supported Platforms:
