在代码中,发现以下错误。
错误在Agrad_descent > @ (x1, x2) ((x1) ^ 2 + 2 * (x2)。^ 2 - 4 * (x1) 2 * (x1.x2))(40行)
f = @ (x1, x2) ((x1)。^ 2 + 2 * (x2)。^ 2 - 4 * (x1) 2 * (x1.x2));
错误Agrad_descent > @ (x) f (x(1),(2))(44)行
f2 = @ (x) f (x (1), (2));
错误Agrad_descent(第128行)
据= f2 (xopt);
编写的代码:
f = @ (x1, x2) ((x1)。^ 2 + 2 * (x2)。^ 2 - 4 * (x1) 2 * (x1.x2));
f2 = @ (x) f (x (1), (2));
据= f2 (xopt);
