k0(x) = <ufunc 'k0'>¶
Modified Bessel function of the second kind of order 0, \(K_0\).
This function is also sometimes referred to as the modified Bessel function of the third kind of order 0.
Value of the modified Bessel function \(K_0\) at x.
The range is partitioned into the two intervals [0, 2] and (2, infinity). Chebyshev polynomial expansions are employed in each interval.
