[proFit-list] Procedure Derivatives

[Andrew Cameron Beveridge]

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[1];

I want the magnitude and phase information for the above function.

y[0] := Abs(x + ii*a[1]);
y[1] := Phase(x + ii*a[1]);

The derivatives with respect to a[1] of two possible outputs are
different.
How would one enter this in the Procedure Derivatives?

Thanks for your help.

Regards,
Andrew
