I have three eqns involving two complex variables w, u and one purely real variable g. One equation is transcendental and complex (involves Bessel functions with the complex variables u, w in the arguments); one is complex-valued but algebraic (can easily be separated into real and imaginary parts); one is purely real (involves g and the real and imaginary parts of one of the complex variables). Any thoughts on whether FindRoot is likely to be happier (i.e., function better) dealing with *three* equations (two complex, one real) involving the three variables w, u and g (including having to write Re[w] and Im[w] in the real equation), or with four equations (one complex, three purely real) involving wr, wi, ur, ui and g , all purely real?
