Hello please help me

Welcome

Please, I need some answers for my questions:

1. How to open .p file and read it .
2. How to save only one variable because when run save, it saved all variables in the program.
3. Can I delete a file on disk by matlab instruction.

Note that the program does not work properly

Thank you

First, read this: http://www.mathworks.com/matlabcentral/answers/13205-tutorial-how-to-format-your-question-with-markup

Then,

1. I don't use p-files but I believe they are opened/run just by typing their name on the command line. They're encrypted so you may not see anything intelligible if you open them in the text editor/debugger window.
2. Put the variable name in single quotes: save(fullFuleName, 'oneVar');
3. Use the delete function: delete(fullFileName);

no open too

You can't. The whole point and reason why someone went to the trouble of converting the MATLAB source code into encrypted p-code is that they don't want you to just open the file in the editor and see the source code .
