Error in save to .txt

Hello, I am having difficulty saving data to a .txt file. The code provided by the research study is

   if save_status == 1
        save Daily_Infectivities.txt c -ascii -double -tabs
        xlswrite('Daily_Infectivities.xlsx', c, 4)
   end

However, I keep getting the error

Error using save
Unable to write file Daily_Infectivities.txt: permission denied.

Error in model_GUI_1_0>pushbutton1_Callback (line 294)
  save Daily_Infectivities.txt c -ascii -double -tabs

Where are you running the code from? Can you switch to a working directory where you do have write capability before doing the save?
