Try this:

Q = marcumq(5, 10);                                     % Create Output
B0 = rand;                                              % Initial Estimate
B = fminsearch(@(b) norm(marcumq(5,b(1)) - Q), B0);     % Result

This is just an example, and it works here. I have no idea if it will work with the variables you will be using, so you may have to experiment with different initial estimates.
