There is no direct function to calculate the value of the derivatives of a Bessel Function, however, one can use the following identity to get it:
J(s-1)(z) - J(s+1)(z) = 2J'(s)(z)
where s, s-1 and s+1 are the orders of the Bessel function and z is the point of evaluation. One can use similar identities for Hankel functions.
