How to update workspace whenever Matlab gets data from server

Hi, guys. I have question. I made server in Unity using C# and client in matlab(TCP/IP). The server sends data to Matlab and Matlab compute transferfuntion after gets data(P, I, D) from Unity. Then, Matlab needs to make data.csv file and Unity read it. I made a Cylinder in Unity and it reads data.csv. Then, Cylinder operates when it reads data.csv. My quesition is that the data.csv file is only generated when TCP/IP is disconnected. I want my data.csv to be updated when TCP/IP is still running.

I think I need to fix while loop in matlab. But, I don't know how to fix it. I hope you guys understand what I'm saying.

cod is below.

while
((s == 2 && data_s(1) == 113) == 0)
    
    type = fscanf(tclient,'%c', 1); 
    data = fscanf(tclient,'%d');
    
    if type == 'P'
        p = data;
       
    elseif type == 'I'
        i = data;
        
    elseif type == 'D'
        d = data;
    
    elseif type == 'T'
        Kavq = 4.17e-6;
        Kce = 6.94e-12*1.1;
        Ap = 1.62e-4;
        Vt = 97e-6;
        Mt = 15.7;
        Be = 10000e5;
        Bp = 1.955e3;
        Kf = 50;
        del_h = Kce/Ap*sqrt(Be*Mt/Vt)+Bp/(4*Ap)*sqrt(Vt/(Be*Mt));
        Wh = sqrt((4*Ap^2*Be)/(Mt*Vt));
        num0 = Kavq/Ap;
        den3 = 1/Wh^2;
        den2 = 2*del_h/Wh;
        den1 = 1;
        den0 = 0;
        num = [ num0 ];
        den = [ den3 den2 den1 den0 ];
        pnum = [ p ];
        pden = [ 1 ];
        inum = [ i ];
        iden = [ 1 0 ];
        dnum = [ d 0 ];
        dden = [ 1 ];
        P1 = tf(pnum,pden);
        I1 = tf(inum,iden);
        D1 = tf(dnum,dden);
        PI = parallel(P1,I1);
        PID = parallel(PI,D1);
        g1 = tf(num, den);
        G = series(PID, g1);
        Gt = feedback(G, Kf);
        t = 0:0.001:5;
        step(Gt)
        y = step(Gt,t);
        u=y';
        Y = round(u,5);
        A= [t;Y];
        fileID = fopen('data.csv','w');
        fprintf(fileID,'%1s,%1s\n','t','Y');
        fprintf(fileID,'%4.4f,%4.4f\n',A);
        fclose(fileID);
        
    
        
    else
        fprintf("Unhandled data.");
              
    end
