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

Parameters:

x (Union[Array, ndarray, bool_, number, bool, int, float, complex]) –
