Matlab 易错总结

'double' 类型的输入参数相对应的函数 'zero'。 ----- 没有zero函数 ,其实应输入zeros

a =0;
hold on
while a < 0.05
    c = [ -0.05,-0.27,-0.19,-0.185,-0.185];
    A = [zeros(4,1),diag([0.025,0.015,0.055,0.026])];
    b = a * ones(4,1);
    Aeq = [1,1.01,1.02,1.045,1.065];
    beq =1;
    LB = zeros(5,1);
    [x,Q] = linprog(c,A,b,Aeq,beq,LB);
    Q = -Q
    plot(a,Q,'*k');
    a = a +0.001;
