scipy.special.k1¶
- scipy.special.k1(x) = <ufunc 'k1'>¶
Modified Bessel function of the second kind of order 1, K1(x).
Parameters: x : array_like
Argument (float)
Returns: K : ndarray
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 [R405] routine k1.
