hello everyone, i want to write a code to calculate these for 121 points
for n = 1:nfreq
T1=[B(n) C(n);D(n) H(n)]
T2=[R(n) G(n);E(n) L(n)]
T=T1*inv(T2)
do you know I could do this?

The code you've already written will calculate those values for each of 121 points.
for n = 1:nfreq
T1=[B(n) C(n);D(n) H(n)]
T2=[R(n) G(n);E(n) L(n)]
T=T1*inv(T2)
end
If you want to save the results of those calculations to use later, you can save the values in an array during the loop. For this case, with each thing you want to save being a matrix itself, I would recommend a cell array.
for n = 1:nfreq
T1=[B(n) C(n);D(n) H(n)];
T2=[R(n) G(n);E(n) L(n)];
T{n}=T1*inv(T2); % The curly braces are used to index in cell arrays
end
% example T
{{[1 2; 4 3]},{[5 3; 7 6]}}
% ^ ^
% T{1} T{2}
% 1 2 5 3
% 4 3 7 6

thank you so much
i tried this but i get error that there is no eig for cell(Undefined function 'eig' for input arguments of type 'cell'.)
ei{n}=eig(T);

then i do ei{n}=eig(T1*inv(T2))
it worked
thank you for ypur help
