I wrote 3 functions and i wanted to link them in main function. In the main function i wrote a while loop . i am facing problem with this while loop. . The loop is running with initial values, i.e., it is not updating the values of rcapa, capaPAMin, and Bineq. The main function runs as follows
How to correct this problem.
global Bineq1; capaPAMin = inf; Bineq2 = capaPAMin; Bineq = vertcat(Bineq1,Bineq2); iter = 1; while(iter <=15) DA2 = @(Bineq,capaPAMin) somefunction(c1,c2,c3,c4,c8,capaPAMin,Aineq,Bineq,Aeq,Beq,lb2,ub2); [yd2,DAC2] = DA2(Bineq,capaPAMin); td2 = yd2(1345:1728); -- -- -- rcapa -- -- PA2 = @(rcapa) somotherfunction(c5,c6,c7,Aineq,Bineq,Aeq,rcapa,lb1,ub1); [yp2,PAC2] = PA2(rcapa); b = yp2(385:576); -- -- capaPA -- -- if capaPAMin > capaPA capaPAMin = capaPA; end Bineq2 = capaPAMin; Bineq = vertcat(Bineq1,Bineq2); iter = iter + 1; end

Please format your code. To do that, select the code in your question, click the {} Code button. That way, it is much easier to read.

In the code you've provided, the variables ( rcapa, capaPA) are not defined.
Moreover even if you define it in the beginning, they are not influenced by any of your functions. So they wouldn't change but stay in its initial conditions.

I am writing below the full code. The loop is not updating the values of rcapa, capaPAMin, and Bineq. How to fix this problem
global Bineq1;
lb = zeros(1,1728);
[yd1,DAC1] = DAgent1([],[],[],[],[],[],[],[],lb,options );
capaPAMin = inf;
iter = 1;
Atd14 = diag(ones(1,192),0);
Atd24 = diag(ones(1,180),12)
Atd4 = Atd14 + Atd24;
O4 = zeros(192,192);
Atd4 = horzcat(Atd4,O4);
sigmatdpfmt = Atd4;
size(Atd4);
td1= yd1(1345:1728);
p1sigmarcapa = diag(ones(1,24),0);
psigmarcapa = repmat(p1sigmarcapa,[1,8]);
size(psigmarcapa);
psigmab = diag(ones(1,24),0);
psigmab = repmat(psigmab,[1,8]);
size(psigmab);
fcapa1 =sigmatdpfmt*td1;
rcapa = fcapa1;
lb1 = zeros(1,576);
PA1 = @(rcapa) PAgent([],[],[],[],[],[],rcapa,lb1,[],[] );
[yp1,PAC1]= PA1(rcapa);
TC1= DAC1 + PAC1;
results = zeros(iter,4);
results(1,1) = 1;
results(1,2) = DAC1;
results(1,3) = PAC1;
results(1,4) = TC1;
b = yp1(385:576);
capaPA = (psigmarcapa*rcapa) - (psigmab*b);
if capaPAMin > capaPA
capaPAMin= capaPA;
end
lb2 = zeros(1,1920);
Bineq2 = capaPAMin;
Bineq = vertcat(Bineq1,Bineq2);
while (iter <=5)
DA2 = @(Bineq,capaPAMin)DAgent( [],[],[],[],[],capaPAMin,[],Bineq,[],[],lb2,[],[] );
[yd2,DAC2] = DA2(Bineq,capaPAMin);
td2 = yd2(1345:1728);
p1sigmarcapa = diag(ones(1,24),0);
psigmarcapa = repmat(p1sigmarcapa,[1,8]);
size(psigmarcapa);
psigmab = diag(ones(1,24),0);
psigmab = repmat(psigmab,[1,8]);
size(psigmab);
fcapa3 =sigmatdpfmt*td2;
rcapa1 = fcapa3;
lb1 = zeros(1,576);
PA2 = @(rcapa1) PAgent([],[],[],[],[],[],rcapa1,lb1,[],[] );
[yp2,PAC2]= PA2(rcapa1);
b1 = yp2(385:576);
capaPA = (psigmarcapa*rcapa1) - (psigmab*b1);
if capaPAMin > capaPA
capaPAMin= capaPA;
end
Bineq2 = capaPAMin;
Bineq = vertcat(Bineq1,Bineq2);
TC2 = DAC2 + PAC1;
results(iter,1) = iter;
results(iter,2) = DAC2;
results(iter,3) = PAC2;
results(iter,4) = TC2;
iter = iter + 1;
end
