DESCRIPTION
DBESKS computes a sequence of modified Bessel functions of the third kind of order XNU + I at X, where X .GT. 0, XNU lies in (-1,1), and I = 0, 1, ... , NIN - 1, if NIN is positive and I = 0, 1, ... , NIN + 1, if NIN is negative. On return, the vector BK(.) contains the results at X for order starting at XNU. XNU, X, and BK are double precision. NIN is an integer.
