Hi !
How can I solve an ordinary differential equation of order n in the
complex plane following a prescribed contour ?
I can of course write my own Runge-Kutta package but is there a quickest
way to do that (maybe NDSolve but how to define the contour ??) ?
Example : NDSolve[{y'[x] == Exp[y[x]], y[1] == 1}, y, {x, 1, 3}]
fails because of a singularity in x=1+1/e.
However integrating the ODE following a path which avoids the
singularity should be possible eventually leading to a multivalued function.
Thanks for a hint.
