I have a .txt file that has two columns. It looks like this
Age 3Salary 52661Average working hours 40Conditions 1, 26, 65, 89, 20, 2, 2
I would like to add a row
Favorite numbers 2, 8, 66
Birdman has given an answer to this question in another topic.
fid=fopen('data.txt','a+');fprintf(fid,'\n%s %d, %d, %d\n',"Favorite numbers",2,8,66);fclose(fid)
Unfortnuately I forgot to add that the amount of doubles (in my case "favorite number"s) can be humongous (hundreds of numbers).
Is there a way to get the %d multiple times in the code without typing it out hundred of times.
I tried
a='%d, ';rep=repmat(a,1,k) %k being the number of favorite numbers
fprintf([fid,'\n%s ' rep ' \n','Favorite numbers', vector_with_numbers]);
this doesn't work, just prints rep. Any ideas?
