is for loop eating my data :)

In the folowing code, the plot is empty .I think that my data is overlapping.

why i have an empty plot , and how can i fix it

dbstop if error

h= 6.626*10^-34 ; % joul.second

[n1]=xlsread('Transmittance-calcs.xlsx');

[n2]=xlsread('Reflectance-calcs.(2).xlsx');

L= 11; % number of rows in excl file

d=900*10^-9; %%total thickness m

for i=1:L;

h= 4.135667*10^-34 ;

A(i) = n1(i,2) ;%%%%% second row which Transmittance

B(i) = n2(i,2) ; %%%%% second row which reflectance

C=(100*A(i));

Q=1./C;

a=(log(Q)/d);

end

for l=200:50:700;

v=(3*10^8)/(l*10^-9);

hv=(h*v)*(6.242*10^18)

ahv2=((a*h*v)*(6.242*10^18)/(100)).^2 %%%% change units from joul/m to ev/cm

end

%plot results:

figure

hold on

plot(hv,ahv2,'b')

You need to store your calculations at each iteration in a vector. E.g.,

k = 0;
for l=200:50:700;
    k = k + 1;
    v=(3*10^8)/(l*10^-9);
    hv(k)=(h*v)*(6.242*10^18)
    ahv2(k)=((a*h*v)*(6.242*10^18)/(100)).^2 %%%% change units from joul/m to ev/cm
end
