I am trying to store data that contains complex numbers into an array. I am having issues on how to setup the loop and extract the data. The error I am getting says "Subscript indices must either be real positive integers or logicals" which is in code line 12.

 i=1;
 for k=10e-10:0.01:10  %discrete reduced frequency range
 Ck = (besselh(1,2,k))./(besselh(1,2,k)+1i*besselh(0,2,k)); %Bessel function
 %Matrices
 A=[0.8132  -0.1008; -0.0725  2.0518]; 
 B=Ck*[7.623  57.15; -8.233  -57.157]; 
 C=Ck*[1865  1473.14; -1119  11907.48]; 
 %frd function
 Hresp=frd(Abar,k);
 H11(i)=Hresp;
 i=i+1;
 end

I would like my output data to look like this:

在 MATLAB Online 中打开

Type this at the MATLAB prompt:

dbstop if error

Then run your code. When the error occurs, the code will pause with all current variables intact. Examine them to figure out why the index you are using is not what you expected it to be.
