MATLAB: Could you like to help to solve a problem with cell arrays in a text file? How could I print these kind of data with the function fprintf

Question

For example, I have a matrix H:

H = [1 2 3; 4 5 6; 7 8 9];

I want to do a file (attached) like:

AB CDEFG 1 2 3

AB CDEFG 4 5 6

AB CDEFG 7 8 9

I wrote this:

fileID = fopen('output.txt','w');
fprintf(fileID,'%2s %5s %1.0f %1.0f %1.0f\r\n','AB','CDEFG',H);
fclose(fileID);

But it doens't work. How can I do this?

Thank you in advance!

Answer 1

fprintf(fileID,'AB CDEFG %1.0f %1.0f %1.0f\r\n', H');
