Converting a matrix of strings to a txt file

Hi there!

I have a mtarix of strings x_mtarix:

x_matrix =

5×3 string array

    "A"        "B"      "C" 
    "AA"       "BB"     "CC"
    "AAA"      "BBB"    " " 
    "AAAA"     " "      " " 
    "AAAAA"    " "      " " 

which I would like to save in a text file that woul contain the x_matrix values keping the same appearance:

A          B          C
AA       BB        CC
AAA    BBB   
AAAA
AAAAA

I have used an assortment of variations of:

fid = fopen('output.txt','wt');
fprintf(fid,'%s\n',x_matrix); 
fclose(fid);

But I dont quite get the results I want

Thanks in advance

1. the format string need to have 3 conversion operators (or as many as you want on each line).
2. the matrix needs to be tranposed.

For example:

fmt = repmat('%8s ',1,3);
fmt = [fmt(1:end-1),'\n'];
fprintf(fid, fmt, x_matrix.')
