3.5.2.4.1.6 Yn

Description

This function returns the nth order Bessel function of the second kind and has the following form:

Yn(x, n)

The formula for the equation is:

Y_n(x,n)=\lim_{v \rightarrow n} Y_n(v, n)

where

Y_n(v,n)=\frac{J_{n}(x,v)\cos(v\pi)-J_{n}(x,-v)}{sin(v\pi)}

Syntax

double yn(double x, int n)

Parameter

x

the input parameter.

n

the order of the Bessel function of second kind.

Return

Returns the nth order Bessel function of second kind at x.

Example

aa = yn(5,3);
aa = ; //0.14626716269319
