I have a question concerning the derivatives procedure if one has a
function with multiple outputs.
For simplicity assume my function is x + ii*a;
I want the magnitude and phase information for the above function.
y := Abs(x + ii*a);
y := Phase(x + ii*a);
The derivatives with respect to a of two possible outputs are
How would one enter this in the Procedure Derivatives?
Thanks for your help.
