I tried using the 'save' function, but I can't seem to get it to work. I want to append a .txt file by saving a variable "excel" to it. I want to be able to do this repeatedly.
I tried the code
save(saving.txt, excel, '-append-')

And I'm sure you got an error message when you run this command. Then it would be a good idea 1. to read the message, and 2. to post it here when the solution is not clear after 1.

save('myFile.txt', 'excel', '-ASCII','-append');

Those are not 9.7 and 1.15 . Those are 97 and 115 which are the character positions of the characters you tried to save. save with -ascii is reserved for numeric values and cannot be used to save text. If you need to save text you will need to fopen/fprintf/fclose . Or there is a hack with dlmwrite. Or Windows with excel installed can xlswrite a cell array containing character vectors. or writetable can write csv files from tables that include character vectors .

Without the -append every save will erase all existing content of the file.
