How could i calculate out Fi_v(0) and the raw values in numerical form from the code below..??

%Inputs Wm = 120; Lembda0 = 1.55; Sigma = 0; nc = 1.456; nf = 1.46;

%Effective width calculation We = Wm+Lembda0/pi*((nc^2)/(nf^2))^Sigma*1/(sqrt(nf^2-nc^2));

%Beat length calculation Lpi = (4*nf*(We^2)/(3*Lembda0)); fprintf('Beat Length, Lpi = %.4f \n \n',Lpi)

%Propagation vector calculation k0=2*pi/Lembda0; fprintf('Free space wave number, k0 = %.4f \n \n',k0)

%Fundamental propagation constant calculation Beta0 = k0*nf- ((pi*Lembda0)/(4*nf*We^2)); fprintf('Beta0 = %.4f \n \n',Beta0)

%Propagation Constant Calculation & plotting X=[]; Vm = 13; for v=1:(Vm-1) Beta = Beta0 - ((v*(v+2)*pi)/(3*Lpi)); fprintf('Beta%d = %.4f \n \n',v , Beta) X(v) = Beta; end y=1:1:12; plot(y,X, '--rs','LineWidth',2,... 'MarkerEdgeColor','k',... 'MarkerFaceColor','g',... 'MarkerSize',5) xlabel('Mode Number'); ylabel('Beta_v');

%Effective index Calculation Q=[]; for v=0:(Vm-1) if v == 0 Neff = Beta0/k0; else Neff = X(v)/k0; end Q(v+1) = Neff; fprintf('Neff%d = %.4f \n \n',v , Neff) end q=0:1:(Vm-1); plot(q,Q, '--rs','LineWidth',2,... 'MarkerEdgeColor','k',... 'MarkerFaceColor','m',... 'MarkerSize',5) xlabel('Mode Number'); ylabel('N_effv');

%eigen mode calculation Fi_v(y) = sin(((v+1)*pi/We)*y); plot(Fi_v(y)) xlabel('Mode Number'); ylabel('Eigen mode');

I am trying to find out the eigen values. But in my graph it starts from 1, but i need to calculate the value for 0 also. Also it will be helpful if i get the values in numerical forms for each of the mode numbers.

And, what does this have to do with the MATLAB Coder Toolbox???
