bessel_i1e

class saiunit.lax.bessel_i1e(x, unit_to_scale=None, **kwargs)

Exponentially scaled modified Bessel function of order 1: \(\mathrm{i1e}(x) = e^{-|x|} \mathrm{i1}(x)\).

Parameters:

• x (Union[saiunit.Quantity, Array, ndarray, number, bool]) – Input array. Must be dimensionless or scaled via unit_to_scale.

• unit_to_scale (Optional[saiunit.Unit]) – If provided, x is scaled by this unit before applying the function.

Returns:

result – Always unitless.

Return type:

Array
