How to put a password by matlab?

Hi everyone

I have some figures produced by a matlab function that I wrote it and then I saved them by "save" matab command. Since they are important I want to protect them therefore I want to put a password on those files. Since there are a huge number of figures and .mat files I need a matlab code to put a password on them.

Is there any matlab command line to put the password on a file?

Any help is appreciated. Regards

Is there a reason the solution has to be through MATLAB? Why not just restrict the permissions on the folder where the files are kept?

There's no facility within matlab to encrypt and password protect a mat or fig file.

However, most OSes have such facilities. If on Windows 7, right-click on a file or directory, select properties, select advanced, and tick 'Encrypt contents to secure data'.
