K = besselk(alpha,x)
K = besselk(alpha,x,1)
K = besselk(alpha,x)computes modified Bessel functions of the second kind for real, non-negative order
alphais a scalar and
xis a vector,
Kis a vector the same length as
xis a vector of length
alphais a vector of length
besselk(alpha(k), x(i)). The elements of
xcan be any nonnegative real values, in any order. For
alpha, the increment between elements must be 1, and all elements must be between 0 and 1000, inclusive.
The relationship between
K and the ordinary Bessel functions
K = besselk(alpha,x,1) computes
besselkalgorithm is based on a FORTRAN program by W.J. Cody and L. Stoltz, Applied Mathematics Division, Argonnne National Laboratory, dated May 30, 1989.
