function f=fun1(x);

f=0.3*x(1)*x(2)+0.7*(x(1)^2+x(2)^2);

function [g]=mycon(x)

g=[1-x(1)^2*x(2);x(2)-x(1);x(1)-4x(2)];

function youh3

clc;

x0=[-1,1];

A=[1];b=[2.5];

Aeq=[];beq=[];

vlb=[0,0];vub=[];

[x,fval]=fmincon(@fun1,x0,A,b,Aeq,beq,vlb,vub,@mycon)

                              输出结果总是错误，这是为什么？

>> fun1

Error in ==> fun1 at 3
