Computes the Bessel i1 function of x element-wise.

    x, name=None

Modified Bessel function of order 1.

It is preferable to use the numerically stabler function i1e(x) instead.


  • x: A Tensor or SparseTensor. Must be one of the following types: half, float32, float64.
  • name: A name for the operation (optional).


A Tensor or SparseTensor, respectively. Has the same type as x.
