How to run a p code matlab?

I have a list of p codes downloaded online. I need to know how to run these files in Matlab? Thanks for all your help!

Answer 1

[Walter Roberson]

pcode files are always functions; just call them the same way as you would any ordinary function.

Answer 2

[Shameer Parmar]

.p files are the end user code, which we can't see like any other .m files.

to run the .p files, simply keep it in your current directory of matlab,

• Method 1:

Right click on file and select 'run'.

• Method 2:

Simply type the filename on command window (without extension).

• Method 3:

Create one .m file, put names of all .p files (without extension) followed by the semicolon, and then run that .m file.

Sami Ullah:

That has nothing to do with p-code.

Answer 3

I came across a very similar situation. You can run them as function files but you got to ""run as administrator" while opening matlab. This enables it to run the .p files as functions.

[Walter Roberson]

You should not need "run as administrator" for most of them. It is possible that some might need to make changes to your configuration so you might need to run as administrator. But I have my usual suspicions about code that cannot be seen and which needs to make changes to protected configuration.

[Jan]

You cannot read the contents of a P-file. If such a function asks for admin privileges, I'd be very suspicious. I would not trust the code without a really good reason: Written confirmation of the author what happens inside and a sha256 hash of the file.

Answer 4

[Kola Murali]

The P-code file D:\videos\matlab\matlab\webcamprot\facewebcam.p was generated prior to MATLAB version 7.5 (R2007b) and is no longer supported. Use pcode to regenerate the file using MATLAB R2007b or later.

what can i do

[Walter Roberson]

You ask the author of the code to generate a new version for you. There is no way for you to "upgrade" the .p file: it needs to be done by someone who has the original .m that the .p file was created from.

It appears to me that the author was probably Luigi Rosa

Looking around, it appears to me that another alternative would be for you to install R2013a or earlier to run the program. (I am not sure which version exactly was the last one the program could be run with.)

i couldn't run .p file in Matlab, please help me out

[Walter Roberson]

Is there an error message?

[Ila Sharma]

yes, in this file one function file named as timebar.p file) is called, and due to .p version it is not running

the error comes as-: Undefined function 'timebar' for input arguments of type 'char'.

Error in SwarmFish_demo_SO_std (line 138) SwarmFish_Procedure_h = timebar('SwarmsLAB::SwarmFish','Total Progress...');

[Walter Roberson]

The version of that in the File Exchange is missing files, it appears. There seems to be a complete version at https://onedrive.live.com/?id=A569FA949D5A7AB5%212372&cid=A569FA949D5A7AB5 . I have verified that timebar.p from there works.
