具有线性和非线性约束的以下优化问题的解决方案是什么？

Question

min x 
subject to: zeta_1>=b
            zeta_2>=h
            t*log(1+m_b*zeta_1)>=t_bh
            (1-t)*log(1+t*m_h*zeta_2)>=t_hb
            0<=t<=1
            ||y||=1,
where zeta_1=(|transpose(a)*y|^2)*x, zeta_2= (|transpose(c)*y|^2)*x. m_b and m_h are parameters. a,c and y are taken from complex numbers and are having dimension N*1. b,h,t_bh and t_hb are constants.

我使用了以下模拟。

    bcd=[5 1];
    ap=[0 0];
    httd=[i -1];
    dist_AB(row)= norm(bcd-ap);
    dist_AH(row)= norm(httd-ap);
    dist_BH(row)= norm(httd-bcd);
    h_AB=raylrnd(dist_AB(row).^(-beta/2),N,200000);
    transpose_a(row,:)=mean(h_AB,2);

    %h_AB1 = cat(3,h_AB1,h_AB);
    h_AH=raylrnd(dist_AH(row).^(-beta/2),N,200000);
    %h_AH1 = cat(3,h_AH1,h_AH);
    transpose_c(row,:)=mean(h_AH,2);
    h_BH(row,:)=raylrnd(dist_BH(row).^(-beta/2),1,200000).^2;
    row=row+1;
end
z=mean(h_BH,2);
m_B=(alpha.*z)/sigma_H;
m_H=(eta.*z)/sigma_B;

所有参数值均从此处计算。我已经为a和c产生了41分。我想找到每个点的最小x值，并与距离作图。如何从这里开始？之后如何使用fmincon。 我还对实际的优化问题进行了一些数学分析，并对其进行了下界。下限的模拟结果是凸函数。我还附了图片
