i0e(x) = <ufunc 'i0e'>¶
Exponentially scaled modified Bessel function of order 0.
i0e(x) = exp(-abs(x)) * i0(x).
x : array_like
I : ndarray
Value of the exponentially scaled modified Bessel function of order 0 at x.
The range is partitioned into the two intervals [0, 8] and (8, infinity). Chebyshev polynomial expansions are employed in each interval. The polynomial expansions used are the same as those in
i0, but they are not multiplied by the dominant exponential factor.
