Hi,
I am trying to create an empty text file using the "save" but is not JUST creating the txt file but is filling with random data.
Here is the line in my code.
save(strcat(path_,filename1,'window_temp_',num2str(window_temp),'.txt')); %temp window
window_temp is just a variable.
I just want to save as empty txt with the name window_temp_15, for example. It's just a way of not having to save my code data manually.
Thank you.

The save() command stores the contents of the current workspace in a MAT file. See:
doc save
To create an empty text file, use fopen():
filename = sprintf('%swindow_temp_%d.txt', filename1, window_temp)
fid = fopen(fullfile(path_, filename), 'w');
fclose(fid)
