You can draw it using meshgrid and surf
[X, Y] = meshgrid(linspace(-3,3));
Z = exp(-X.^2-Y.^2);
surf(X,Y,Z)
shading interp

FYI, this is a faster version of the previous code in the comment
syms x y X Y
fun = matlabFunction(int(int(z,x,0,X),y,0,Y), 'Var', {X, Y});
[Xg, Yg] = meshgrid(linspace(0,2));
Z = arrayfun(fun, Xg, Yg);
surf(Xg,Yg,Z)
shading interp
