I implement fdf using numerical partial differentiation of f. This method (numerical partial differentials) appeared to work; is this a reasonable approach?
Yes, the df and fdf functions need to caluclate the numerical partial derivatives given the current values of the arguments (vector x in the docs) and your independent variable data.
To my knowledge, the approach you took is the only reasonable approach. Barrett Foat
