If you have a function in terms of its real and imaginary components,
and you know that the function is differentiable,
Dear R experts,
I'd like to take analytic derivative of complex functions through D
function. I succeded with simple functions like sin(x), but what if
I want to work with function like A(x,y, ...) + i*B(x,y, ...)?
Thank you.
