MATLAB: Fsolve with arguments

fsolvefunction

Can I call a fsolve funciton with arguments? I was trying to do somethink like this:
root2d.m file:
function (F) = root2d(x)
F(1) = x(1)*E+x(2)- x(2)*(x(1)^2); F(2) = x(1)*cos(x(2)) + x(2)*sin(x(1)) – E;
and calling the function: fun = @root2d; E = 23; x0 = [0,0]; x = fsolve(fun,x0);
So how can i call fsolve function for diferents values of E ?

Easiest way to do this is with a nested function. The nested function can see its parent workspace.
function x = fsolveex(E)
x0 = [0,0];
x = fsolve(@root2d,x0);
      function F = root2d(x)
          F(1) = x(1)*E+x(2)- x(2)*(x(1)^2); 
          F(2) = x(1)*cos(x(2)) + x(2)*sin(x(1)) - E;
      end
end
Now just pass E values into fsolveex
x = fsolveex(23)
