The Bessel function cross product arise in problems on an annulus, and the roots of these need to be found to solve certain boundary value problems.
This function uses Olver's uniform asymptotic expansion to find an initial guess at the roots of the desired Bessel function cross product, then updates via Newton's method. The method works over a large range of radius ratio and order.
