3.5.1.3.65 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:
/math-6c279ef193e24f7a058a3e4d323a0468.png?v=0 "Y_n(x,n)=\lim_{v \rightarrow n} Y_n(v, n)")
where
/math-9ffe2af4b0f7599e4842b7771056b13d.png?v=0 "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
