disable your antivirus, that may be the cause for not being able to save your diary, especially in .txt , I work after I disable it. My antivirus is AVG.

The folder where MATLAB is configured to save your diaries has no writing permission. You can either change the folder permissions (by default, inside your MATLAB installation folder, located at: /bin/win32 or /bin/win64), or run MATLAB as Administrator. I had the same problem and now it is working.

I strongly advise you not to create new files or modify existing files inside your MATLAB installation. Changing the current directory or creating a full file name (with path, using fullfile or something similar) and using that with diary would be my recommendations. You can't run this in MATLAB Answers (the diary function isn't supported) but you could in your local installation of MATLAB.

fn = tempname % Random temporary file name
diary(fn)
peaks % Will display in the diary file
diary off
type(fn)

It seems you are trying to execute that command in a folder where you don't write permission.

Can you cd to a folder where you have write permission and try that command again?

Diary IS working, merely doing what it is capable of doing. Your operating system is preventing MATLAB form doing as you desire.

You don't have write access to the current directory. Read the error message. MATLAB is telling you it cannot open the file.

The fix? Simple. Either change your current directory to one where you DO have write access, or change the access privileges on that directory if you have permission to do so. You should also be able to specify a complete path for the diary file, into a directory where you again have write access.

very simple answer just create new folder on desktop etc right click on it and copy path and paste on command window after write cd like this >> cd 'path' or cd 'C:\Users\Adeel011\Desktop\example-folder' thankx and enjoy
