MATLAB: How to store matrix data (Imaginary) from a loop

for loopmatrixmatrix array

Hello, In my project I have a loop and each iteration gives me a matrix with imaginary values:
    for fi = 0:10000:1100000
     ....
    A1=[a11,a12;a21,a22]
    end
Output:
    A1 =
   1.0e+02 *
  -0.0934 + 0.0245i  -9.0639 + 3.2366i
  -0.0010 + 0.0002i  -0.0934 + 0.0245i
I need to store all this matrixes with relation to fi value. I am going to use few similar loops and multiply output matrixes (for the same value of fi).
I try to use
    A1(fi)=[a11,a12;a21,a22]
but have below error:
Subscript indices must either be real positive integers or logicals.
Can I please any ideas and tips? 🙂

    fivals = 0:10000:1100000;
    numfi = length(fivals);
    A1 = cell(numfi, 2);
    for fiidx = 1 : numfi
      fi = fivals(fiidx);
      ....
      A1{fiidx, 1} = fi;
      A1{fiidx, 2} = [a11,a12;a21,a22]};
    end
Now A1 will be an N x 2 cell array in which the first column is the fi values and the second column is the A1 arrays that resulted.
