Scott,
Try FindRoot. As an example...
FindRoot[Gamma[z] == 2 + 3*I, {z, 1}]
{z -> -1.1423913504357908 + 0.2086374207214744*I}

I have an equation, Gamma[a+I b] = some complex number. I need to
solve this equation for a and b. I can write a+I b as z, but it can't
be solved through NSolve. What I have been doing is a double do loop
for a and b and getting some number. Then I compare this to the
number I have. Then I narrow down my possibilities for a and b, and
go through the process again. Does anyone know of a better way to do
this problem? Is there a way to have Mathematica compare each result
of the do loop to a given value, and given certain conditions spit out
an answer for a and b?
Hope that makes sense.
