How to invert .p file to .m file

I have a file with a .p extension. How can I convert to .m file?

[recent works]

not possible. only .m files to .p files possible.

You cant do that.

In this section you will practice writing .m-files to calculate the basic attributes of continuous-time signals. Download the function signal1.p . This is a pre-parsed pseudocode file (P-file), which is a “pre-compiled” form of the Matlab function signal1.m. To evaluate this function, simply type y = signal1(t) where t is a vector containing values of time. Note that this Matlab function is valid for any real-valued time, t, so y = signal1(t) yields samples of a continuous-time function.

How can I do that?

[John D'Errico]

The question did not tell you to convert the file to an m-file. It told you to use it. So what is the problem? Nothing stops you from using a p-file.

If you're not sure what your professor has asked you to do, you probably need to ask them to clarify.

From the portion of your assignment that you've quoted, it doesn't sound like your professor wants you to reverse engineer the signal1 function. It sounds like they want you to treat it as a "black box" and write code that uses the signal that black box emits.

"How can i solve this problem?"

What problem? You can use that .p file without converting it to anything else (that is the whole point of them). The task you were given even tells you exactly how: "To evaluate this function, simply type y = signal1(t) where t is a vector containing values of time".

not possible. only .m files to .p files possible. mainly .p files helps to protect the important files

Answer 3

[Benjamin Kraus]

By design, there is no way to convert a P-coded file (a file with the .p extension) into a regular MATLAB file (a file with the .m extension). The conversion from MATLAB file to P-coded file is a one-way conversion. As the description on the pcode doc page ("Create protected function file") states, the purpose of creating a P-coded file is to obfuscate the code to protect the source code. If you could reverse the operation, there would be no point in converting to a P-file.
