<pre>=besselj(3.8,2) gives .409. Good
=besselj(3.8,-2) gives err502. Bad. It should give the same answer
=besselj(3.8,3) gives .418. Good
=besselj(3.8,-3) gives err502. Bad. It should give -.418
In general
besselj(x,-even order)=besselj(x,+even order) (behaves like cos(-x)=cos(x))
besselj(x,-odd order)=-besselj(x,+odd order) (behaves like sin(-x)=-sin(x))
