can someone take a look at my code and tell my why its not outputing the paritial derivatives of fx and fy
the instructions were
Plot the function f (x, y) = 2x3y − y2 − 3xy.
Find fx and fy using the diff command. Setting these to zero, solve the resulting system of
equations using the solve command.
i used both diff command and solve command im not getting an error message for my lines of code but the code doesnt output an answer my code is below
f=@(x,y) 2*x^3*y - y^2 - 3*x*y;
syms x y;
G = [diff(f,x); diff(f, y)];
solve x y

f=@(x,y) 2*x^3*y - y^2 - 3*x*y;
syms x y;
G = [diff(f,x); diff(f, y)];
sol = solve(G, [x y])
subs([x, y], sol)
