code for calculate points
显示 更早的评论
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

I recommend you do the eigenvalue operation in the same loop, so you don't have to loop twice (I think it should save some time). You can use the eig function to get the eigenvalues (and eigenvectors if needed) and can save the results in the same way as the matrices are saved.
If you have any further questions I recommend you make another question so that all of the site can easily find it.
