WHat correction?

I can't run your code as you post it.

EDU>> gamma = real(gamma)+1j*imag(gamma)
Error using gamma
Not enough input arguments.

EDU>> gr1 = sqrt(-100 - gamma^2);
Error using gamma
Not enough input arguments.

You should post complete, selft contained code that
runs. Make sure it is all in segment, clearly delimited
so someone who wants to copy it, knows where it starts
and where it ends.

So, try again. Post complete working code, then
may be you'll have better chance of someone helping
you better.

good luck,
