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
