MATLAB: Displaying matrix in .txt file (fprintf)

Question

Hello.

I have matrix with complex numbers with different numbers of digits. I want to print them to the file but they are not aligned.

|1.00+0.00i            1.00+0.00i            1.00+0.00i            1.00+0.00i|
 |0.00+0.00i            -49.00+4.00i            -49.00-4.00i            -52.00+0.00i|
 |0.00+0.00i            -2417.00-0.00i            -2417.00+0.00i            -2392.00+0.00i|
 |0.00+0.00i            -117649.00-64.00i            -117649.00+64.00i            -117676.00+0.00i|

I need something like this:

 |1.00+0.00i                  1.00+0.00i                   1.00+0.00i                   1.00+0.00i|
 |0.00+0.00i                -49.00+4.00i                 -49.00-4.00i                 -52.00+0.00i|
 |0.00+0.00i              -2417.00-0.00i               -2417.00+0.00i               -2392.00+0.00i|
 |0.00+0.00i            -117649.00-64.00i            -117649.00+64.00i            -117676.00+0.00i|

This is code that I print it into file

 for k=1:n
        fprintf(fileID,' |%.2f%+.2fi            %.2f%+.2fi            %.2f%+.2fi            %.2f%+.2fi|\r\n',[real(A(k,:));imag(A(k,:))]);
    end
    fprintf(fileID, '\r\n\r\n\r\n');

Is there any way to make this matrix more aligned?

Just tweaked you code itself a little bit:

fileID=fopen('MyFile.txt','w'); % Open text file for writing
 for k=1:3
        fprintf(fileID,' |%.2f%+.2fi            %10.2f%+.2fi            %10.2f%+.2fi            %10.2f%+.2fi|\r\n',[real(A(k,:));imag(A(k,:))]);
 end
 fprintf(fileID,' |%.2f%+.2fi            %10.2f%+.2fi           %10.2f%+.2fi           %10.2f%+.2fi|\r\n',[real(A(4,:));imag(A(4,:))]);
 fprintf(fileID, '\r\n\r\n\r\n');
fclose(fileID); % Close the file

Gives:
