old p code #6

Closed atpage closed 8 years ago

atpage commented 8 years ago

When running first_simple_example.m I get the following error:

The P-code file <...>/common/prtools_addins/private/covm.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.

This is in MATLAB 2015b. I suspect the same issue will occur with other p files in the project as well.

Hi atpage, thanks for the feedback !

I run the same example in r2015a without problem. I will move this to the forum and try to provide more details about your system and what where and when the problem occurs.

Kind regards, M.

Sorry I mean, ask this in the forum at

and lets try to solve this.

Hi Mariano, It seems pretty straightforward: http://www.mathworks.com/help/matlab/ref/pcode.html

If your P-file was generated prior to MATLAB 7.5, it will not run in MATLAB 8.6 (Release R2015b) or later.

So you're just one update away from it happening to you! It looks like you simply have to re-run pcode(function) in a newer copy of MATLAB to generate an updated p file. Unfortunately, we (users) can't, because we don't have the original code.

Alex, PRtools is a sepparate toolbox that I don't administer and therefore, I can't recompile. You can download PRtools by yourself and replace by the one included in ecg-kit/common folder. Keep me updated if this corrects the problem, since I can not replicate this problem in r2015a.

Best, M.

Great, thanks for the tip! I was able to download PRTools from their website, and have recompiled the .p files using their source code. Pull request is here: https://github.com/marianux/ecg-kit/pull/7 . Note that the .p files actually aren't even required now, because the .m files are complete, but you may still want them for performance reasons.
