BesselJ

Computation of the Bessel J-function, Anger J-function, Weber E-function, and Anger-Weber function, of a complex variable.

The order of the Bessel J-function implemented in this package can be a complex number with real part larger than -0.5, or any integer. There is no restriction for the Anger J-function and the Weber E-function. For the Anger-Weber function, the order must be a non-integer complex number with real part larger than -0.5.
