Hi,

in how many dimensions do you want to plot that function? It appears that you have 4 independent variables and one dependent variable. Do you want to plot that in four dimensions and then colour-code the value? Even if you were to plot in the three available spatial dimensions, colour code the value of f and then use "time", i.e. make a video, for the remaining variable it would be very difficult to plot.

Can you show a figure of a function of four independent variables that shows how you want it to be plotted? There are tricks of visualising that, but it would be good to understand your ideas of how you want this to be represented.

fyi, a function in Mathematica is defined using _ as in f[w_,x_,y_,z_]:=. btw, your functions always seem to generate very large values: N@f[1, 1, 1, 1] gives 1.9489499245*10^21714 which is really a large number. Is there a way you can normalize your function first?
