matlab定义函数句柄_matlab的fmincon函数

% min F(X)
% s.t
% AX <= b
% AeqX = beq
% G(x) <= 0
% Ceq(X) = 0
% VLB <= X <= VUB

clear
clc
x0 = [1; 1];  %初始值！ 
A = [2, 3; 1, 4];
b = [6, 5];
Aeq = [];
beq = [];
VLB = [0; 0];
VUB = [];

%[x, fval] = fmincon(@fun3, x0, A, b, Aeq, beq, VLB, VUB)  %两种都可以，后者可以传递参数
[x,fval]=fmincon(@(x) fun3(b,x), x0, A, b, Aeq, beq, VLB, VUB);

function f = fun3(b,x)
f = -x(1) - 2*x(2) + (1/2)*x(1)^2 + (1/2)*x(2)^2;
