Use BESSELY function to calculate the Bessel function of the first kind Yv(z). For non-integer v, the BESSELY function is defined by
In the case of integer order n, the function is defined by taking the limit as non-integer v tends to n
Syntax
SELECT [wctEngineering].[wct].[BESSELY] (
<@x, float,>
,<@n, float,>)
Arguments
@x
is the value at which to evaluate the function. @x is an expression of type float or of a type that can be implicitly converted to float.
@n
is the order of the Bessel function. @n is an expression of type float or of a type that can be implicitly converted to float.
Return Types
float
Remarks
· @n is truncated to zero decimal places.
· If @n is less than zero, BESSELY returns an error
Examples
select wct.BESSELY(2.5,1)
This produces the following result
