Do dlgradient and dlfeval have to be used together?
function [y,dydx] = rosenbrock(x)
y = 100*(x(2) - x(1).^2).^2 + (1 - x(1)).^2;
dydx = dlgradient(y,x);
end
[y,dydx] = rosenbrock([1,2]),
get error??? Value to differentiate must be a traced dlarray scalar.
Can't it be as convenient as pytorch?”a traced dlarray scalar.“ not clear!!!

x=[1,2];
[y,dydx]=rosenbrock(x);
