Y = bessely(alpha,x)
Y = bessely(alpha,x) computes Bessel functions of the second kind for real, non-negative order alpha and argument x. If alpha is a scalar and x is a vector, Y is a vector the same length as x. If x is a vector of length m and alpha is a vector of length n, then Y is an m-by-n matrix and Y(i,k) is bessely(alpha(k), x(i)). The elements of x can 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.
bessely algorithm is based on a FORTRAN program by W.J. Cody and L. Stoltz, Applied Mathematics Division, Argonnne National Laboratory, dated March 19, 1990. This program is available on NETLIB.
