Legacy Name: bessely
Computes the Bessel function of the second kind of a given order.
Name  Description 

v  Specifies the order of the Bessel function. v is a real, doubleprecision, floatingpoint, positive scalar, vector, or matrix. 
x  Specifies the value for which you want to compute the Bessel function. x is a real or complex, doubleprecision, floatingpoint scalar, vector, or matrix. 
1  Scales the computation. bessel_y(v, x, 1) scales bessel_y(v, x) by exp(abs(imag(x))). 
Name  Description  

yv  Returns the Bessel function of the second kind. yv is a real or complex, doubleprecision, floatingpoint scalar, vector, or matrix.  
error  Returns error information about the evaluation of the Bessel function. error is a matrix of integers in which each element can return the following values.

bessel_y(v, x) solves the following equation: x^{2}*w''+x*w'+(x^{2}v^{2})*w = 0.
The following equation is a wellknown representation for bessel_y(v, x): bessel_y(v, x) = (bessel_j(v, x)*cos(v*pi)bessel_j(v, x))/sin(v*pi).
The following table lists the support characteristics of this function.
