jax.scipy.special.exp1#
- jax.scipy.special.exp1(x, module='scipy.special')[source]#
Exponential integral E1.
LAX-backend implementation of
scipy.special.exp1().Original docstring below.
For complex \(z \ne 0\) the exponential integral can be defined as [1]
\[E_1(z) = \int_z^\infty \frac{e^{-t}}{t} dt,\]where the path of the integral does not cross the negative real axis or pass through the origin.
- Returns:
Values of the exponential integral E1
- Return type:
scalar or ndarray
