mindspore.ops.bessel_j1

mindspore.ops.bessel_j1(x)

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

\[\begin{split}\begin{array}{ll} \\ J_{1}(x) = \frac{1}{\pi} \int_{0}^{\pi} \cos (x \sin \theta- \theta) d \theta =\sum_{m=0}^{\infty} \frac{(-1)^{m} x^{2 m+1}}{2^{2 m+1} m !(m+1) !} \end{array}\end{split}\]

Parameters

x (Tensor) – The input tensor.

Returns

Tensor

Supported Platforms:
