Hi.
I have a non-linear equation including bessel functions with complex argument,as following:

my_equation=(w*sqrt(k^2-100)*besseli(1,sqrt(k^2- w))*besselk(0,sqrt(k^2-100))+...
besselk(1,sqrt(k^2-100))*besseli(0,sqrt(k^2- w)));
that:
k is complex unknown (k = real(k) +1j*imag(k))
w is real unknown.
I want to obtain a relation between imag(k) and w,and also a relation between real(k) and w.
but I don't know how do it.
is there anyon who help me?
thanks...
ghasem
