=BESSELJ(X,N)
=BESSELJ(1.9,2)
The BESSELJ function is used in Sourcetable to calculate the Bessel functions of the first kind. An example of using this function is above, which returns the 2nd order Bessel function evaluated at 1.9.
The BESSELJ function is used to calculate the n-th order Bessel function of a variable using the Gamma function. Note that errors occur if n is not an integer or is not a number, or if n is less than 0.
