Usage INTEGER N

REAL X,Y

Y=FNS_khn(N,X)

Description

FNS_khn returns the value of the modified spherical Bessel function of the third kind and order n+½ of x, kn+½(x). Kn+½(x) is defined for all values of n and for all positive values of x.

Errors

FNS_khn causes an HTBasic error if its arguments are not of the types shown in the USAGE section, above, or if x is negative or zero.

Note

The algorithm used computes the value of kn+½ using a recursion from the values of k½ and k1½. The computation time increases with n and the computation accuracy decreases with n.
