How do I save a workspace variable to a .txt file?

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-')

Just to be clear. Your variable is called excel?

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');

That worked well. How about text? This is the code I put in

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

Here's the output I got that ended up in the .txt file

 9.7000000e+001  1.1500000e+002  1.0000000e+002  1.0200000e+002    5.9000000e+001  1.0800000e+002  1.0600000e+002  1.0700000e+002   9.7000000e+001  1.1500000e+002  1.0000000e+002  1.0200000e+002

[Cg Gc]

Has anyone figured out how to remove the 10power?

Hello, what is '-append' stand for ?

I tried without '-append', also worked.

Thank you!

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.
