I do not suggest to use NDcost, which should not have been integrated 
into Scilab anyway.

Indeed, this macro has only 2 lines where the first one calls f, and the 
second one calls derivative. We can customize the cost function directly 
ourselves, which has the major advantage of being able to fully 
customize the options of the derivative function. Moreover, we can use 
the full potential of the printing options provided by the optim 
function, which is not possible with NDcost.

Best regards,

Michaël Baudin
