I have a stupid problem and cannot find a solution anywhere. I have
func[x_,y_] := 3/Pi*(1 - x^2 + y^2))^2
which I need the Laplacian of:
funcLapl := Laplacian[func[Xx,Yy]]
The Laplacian is computed correctly, but how can I treat the result as
a function? I want to be able to evaluate/plot the Laplacian. I tried
many things and I'm frustrated. My current solution is to manually
copy the derived Laplacian and create a function from that. It's
obviously not a good solution.
