  • name (str, optional) – For details, please refer to Name. Generally, no setting is required. Default: None.

Returns

  • out (Tensor), A Tensor. the value of the modified bessel function of order 1 at x.

Examples

import paddle

x = paddle.to_tensor([0, 1, 2, 3, 4], dtype="float32")
print(paddle.i1(x))
# (Tensor(shape=[5], dtype=float32, place=Place(cpu), stop_gradient=True, [0., 0.5651591 , 1.59063685 , 3.95337022 , 9.75946515]),
