How to specify the gradient of this function?

Hi, If I could ask you to take a look at this code: objF[x_, v_] := (x - 2)^4 + Norm[v]^2; FindMinimum[objF[x, v], {{x, 1}, {v, {1, 1, 1, 1}}}, StepMonitor :> Print[x, " ", v]] My objF takes a number and a vector. Is there a way to specify a gradient for a function with such a mix of inputs? Many thanks in advance, Sam
