Use BESSELJ function to calculate the Bessel function of the first kind J±v(z). The BESSELJ function is defined by
Syntax
SELECT [wctEngineering].[wct].[BESSELJ] (
<@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, BESSELJ returns an error
Examples
select wct.BESSELJ(1,5)
This produces the following result
