►A comprehensive and powerful approach is to integrate the differential equations (13.2.1) and (13.14.1) by direct numerical methods.
As described in §3.7(ii), to insure stability the integration path must be chosen in such a way that as we proceed along it the wanted solution grows in magnitude at least as fast as all other solutions of the differential equation.
►For and this means that in the sector we may integrate along outward rays from the origin with initial values obtained from (13.2.2) and (13.14.2).
…
►In the sector the integration has to be towards the origin, with starting values computed from asymptotic expansions (§§13.7 and 13.19).
On the rays , integration can proceed in either direction.
