scipy.special.k1#
- scipy.special.k1(x) = <ufunc 'k1'>#
Modified Bessel function of the second kind of order 1, \(K_1(x)\).
- Parameters
- xarray_like
Argument (float)
- Returns
- Kndarray
Value of the modified Bessel function K of order 1 at x.
Notes
The range is partitioned into the two intervals [0, 2] and (2, infinity). Chebyshev polynomial expansions are employed in each interval.
This function is a wrapper for the Cephes [1] routine
