Description Returns the Bessel function.
Bessel functions, are canonical solutions y(x) of Bessel's differential equation:
Syntax BESSELJ(X, N) The BESSELJ function syntax has the following arguments:
- X Required. The value at which to evaluate the function.
- N Required. The order of the Bessel function. If n is not an integer, it is truncated.
- If x is nonnumeric, BESSELJ returns the #VALUE! error value.
- If n is nonnumeric, BESSELJ returns the #VALUE! error value.
- If n < 0, BESSELJ returns the #NUM! error value.
- The n-th order Bessel function of the variable x is:
where:
is the Gamma function.
