jax.scipy.special.i1#
- jax.scipy.special.i1(x)[source]#
Modified Bessel function of order 1.
LAX-backend implementation of
scipy.special.i1()
.Original docstring below.
Defined as,
\[I_1(x) = \frac{1}{2}x \sum_{k=0}^\infty \frac{(x^2/4)^k}{k! (k + 1)!} = -\imath J_1(\imath x),\]where \(J_1\) is the Bessel function of the first kind of order 1.
- Parameters:
x (array_like) – Argument (float)
- Returns:
I – Value of the modified Bessel function of order 1 at x.
- Return type:
scalar or ndarray
