Hi,

I would like to write a code whith two arrays as inputs: W_C and L_C

I want to calculate some formulas for each value. for instant:

W_C=[ 1 2 3 4]

L_C=[ 5 6 7 8]

I want to calculate all for mulas when:

W_C = 1 and L_C=[5 6 7 8]

W_C= 2 and L_C=[5 6 7 8]

.

W_C=4 and L_C=[5 6 7 8]

So, I should have 16 results. Here is a code I'm thinking of. however, I get following error:

Index in position 2 exceeds array bounds (must not exceed 1).

Thanks

Here is the code:

clc;
clear all;
close all;
W_C=[0.35 0.5 0.65 0.80];
L_C=[3 4.5 6 7.5];
H=0.035;
epsilon_r=3.38;
for i=1:length(W_C)
   W_C=W_C(1,i);
         epsilon_o=8.85418782*10^(-12);
         epsilon_re=0.5*(epsilon_r+1)+0.5*(epsilon_r-1)*(1+12*(H./W_C)).^(-0.5);
         C_I=0.5*epsilon_o*(epsilon_r+1)*(5.5.*L_C);
         L_series=50*(1/(3*10^(8)))*sqrt(epsilon_re).*L_C;
         R_s=1.5*10^(-6)*sqrt(2.6*10^9);
         R_series=(4/3).*(L_C./(6.*W_C))*R_s;
end
disp(C_I)
disp(L_series)
disp(R_series)

Is this what you want?

clc;
clear all;
close all;
W_C=[0.35 0.5 0.65 0.80];
L_C=[3 4.5 6 7.5];
H=0.035;
epsilon_r=3.38;
for i=1:length(W_C)
    W=W_C(1,i);
    for k=1:length(L_C)
        L = L_C(k);
        epsilon_o=8.85418782*10^(-12);
        epsilon_re=0.5*(epsilon_r+1)+0.5*(epsilon_r-1)*(1+12*(H./W)).^(-0.5);
        C_I=0.5*epsilon_o*(epsilon_r+1)*(5.5.*L);
        L_series=50*(1/(3*10^(8)))*sqrt(epsilon_re).*L;
        R_s=1.5*10^(-6)*sqrt(2.6*10^9);
        R_series=(4/3).*(L./(6.*W))*R_s;
        fprintf('W = %.2f, L = %.2f, C_I = %.6f, L_series = %.6f, R_series = %.6f\n', ...
