Is it possible to make a line of my matlab program invisible and at the same time include that line while running the program?

I wish to hide those lines from the screen

[Jan]

Do you mean a line in a diagram, or line of code? What does "from the screen" exactly mean: Where should vanish what?

[sherry holmes]

I mean a line of code.

Sorry, but no. Well, and yes, to some extent. How is that for a definite answer? It kind of depends on what you really want to do here.

At best, you could define it in a separate file, then p-code the file to be un-viewable. Nobody can read/view p-coded files.

If it is just that you don't want to see the code yourself, then you can fold it up in the editor. That effectively makes it as if it is not seen.

And again, you can always put something in a separate m-file, then just call that function (or script).

"Nobody can read/view p-coded files." - Do not overestimate the protection level of P-coded files. It is a valid and reliable method for obfuscating the code, but not a strong encryption.

After a P-file is imported to Matlab, you find it in the memory dump. Then the main protection is that all users have accepted the license conditions, which forbid a reverse-engineering.

Yes, it is theoretically possible. Lots of things are so. For example, theoretically, we should already have manned missions on their way to Mars. But practicality is often at odds with theory.
