Saving notes to the startup function

I have an editable text area in my app and I would like to save the changes in it automatically to the startup function (this way next time that I will open the app I will see the notes from the last session). Can it be done?

That would not follow good practice: you should keep data and code separate, especially when that data is being changed. Just save the data in a .mat file and load that: simple.

Any specific reason why you want to do this in the start fcn? IMHO, the best way is to store the data in a separate file (example text, mat etc).

If you are, for some reason you need it, you will have to open the .m file using fopen and fwrite commands.
