Hi Andrea,<div><br></div><div>The problem with the approach you suggest is that the evaluation of jacobian() and the other drivers would return, in addition to the "true" derivatives, the derivatives of the dependent variables with respect to those "fake" independent variables, right?</div>

Thanks for your reply. I'll have to retape then.<br>

Retaping is always costly. Another approach would be to introduce these parameters as additional independent variables. Then you could provide the<br>
modified values together with the "real" independent variable such that<br>
the modified values are taken into account during the derivative calculation.<br>
