Thanks Giles! I was looking in the wrong place. Any suggestions on examples for these classes (a math function example would be very nice)? I've found this link (very helpful) but I don't know what to code in the gradient method. In ParametricUnivariateFunction.value I just returned my function output with the params as arguments (plus x). For gradient, I'm in a pitch.
ps: the mailing list was refusing my mails with my other email account (don't
know why). So, I'm responding through here.
