I am stuck with a problem I cannot solve.= I would like to call a previous equation into the function Function. If a = type directly the expression or copy paste it, it works. However, when I ca= ll the expression by its name it does not. > Here is the code for a more precise explanation: > > In: ll > Out: d + a x + h x^2 + b y + e x y + c z + j z^2 > > In: Function[##, a x + b y + c z + d + e x y + h x^2 + j z^2] & @@ {Listp= } > Out: Function[{a, b, c, d, e, h, j}, > a x + b y + c z + d + e x y + h x^2 + j z^2] > > It works well and I can use it to generate as many equations I want by re= placing the variables a,b,c,d,e,h,j. > But if I do: > > In:Function[##, ll] & @@ {Listp} > Out:Function[{a, b, c, d, e, h, j}, ll] > > And I cannot use it. > > Any suggestions?
