Code to produce v1
This code takes the input of the Y1 matrix and the initial impedance to produce a vector of v1 values, using equations discovered in previous research. This code also produces v2 as well as yin which is not needed for our purposes.
%function to produce values for v1 given a Y1 and S0
function v1 = nfc(Y1,S0)n = 41;
Z0 = 50;A = S0;
S = zeros(n,n);for k = 1:n,
for l = 1:n,S(k,l)=A(k,2*l1)*cos(A(k,2*l)*pi/180)+i*A(k,2*l1)*sin(A(k,2*l)*pi/180);
endend
Zparam = Z0*inv(eye(n)S)*(eye(n)+S); % Zparameters of nport systemYparam = inv(Zparam);
W = Yparam; % Ys matrixm = 20; % Number of receivers
r = n1; % Maximum n1W11 = W(1:m,1:m);
W12 = W(1:m,(m+1):r);W13 = W(1:m,r+1);
W21 = W((m+1):r,1:m);W22 = W((m+1):r,(m+1):r);
W23 = W((m+1):r,r+1);W31 = W(r+1,1:m);
W32 = W(r+1,(m+1):r);W33 = W(r+1,r+1);
Yc = inv(W22  W21*inv(W11)*W12 + Y1); % Complex Y matrixY = real(Yc); % Matrix M in paper
YY = imag(Yc); % Matrix N in paperP = W22W21*inv(W11)*W12; %*****W11+Y1 changed to W11
P1 = W31*inv(W11)*W12W32; %*****W11+Y1 changed to W11M = real(P);
M = 0.5*(M+M');v2 = P1*(Y+YY*i); % Voltages as input to Y1
v1 = v2*W21*inv(W11)W31*inv(W11); % Voltages not connected to Y1 %*****W11+Y1 changed to W11yin = v1*W13+v2*W23+W33;
return
Using this code, we could feed the function a variety of Y1 values to try and determine a pattern between the Y1 and the v1. This way, we were able to modify Y1 in whichever fashion we liked to see if there were visible patterns that could be seen within the v1 values. The code that calls this function then uses the value of v1 and Y1 to plot graphs and look at specific values.

what is fullerene does it is used to make bukky balls
are you nano engineer ?
s.
fullerene is a bucky ball aka Carbon 60 molecule. It was name by the architect Fuller. He design the geodesic dome. it resembles a soccer ball.
Tarell
what is the actual application of fullerenes nowadays?
Damian
That is a great question Damian. best way to answer that question is to Google it. there are hundreds of applications for buck minister fullerenes, from medical to aerospace. you can also find plenty of research papers that will give you great detail on the potential applications of fullerenes.

so some one know about replacing silicon atom with phosphorous in semiconductors device?
Yeah, it is a pain to say the least. You basically have to heat the substarte up to around 1000 degrees celcius then pass phosphene gas over top of it, which is explosive and toxic by the way, under very low pressure.
