MATLAB wrapper on Macbook Air M1 not understanding architecture #619

Closed Mansi-zei closed 6 days ago

Mansi-zei commented 2 months ago

Description

I am having trouble getting the MATLAB wrapper to work on my Mac air. I have successfully built the CMake directory, and followed each of the steps on the legacy instructions, but when I try to use refpropm (downloaded from the legacy folder and also placed in the refprop directory off my home directory), the following error message appears:

>> refpropm('T','P',101.325,'Q',0,'WATER')
Error using refpropm (line 215)
Architecture[MACA64] is not understood

I have attached an image of the file structure on my laptop below. I would have tried to follow the more updated instructions, but they seem to be set up for a Windows interface. Is there a MacOS version of this wrapper beyond the legacy one?

One possible issue I am considering is that my cmake build is on my desktop (home/desktop/refprop-build/cmake-build) and the refprop directory is in my home directory (home/refprop), but it does not seem that that's the problem? I've copied over the files and folders listed as necessary, so I don't think this is actually an issue.

Versions

REFPROP Version: 10
Operating System and Version: MacOS Sonoma 14.5, Macbook Air M1 (arm64 architecture) Access Method: MATLAB R2024a via Python 3.12 with standard installations (IDLE interface)

The refpropm interface is no longer supported. Please switch to the Python-based one for MATLAB. What architecture is your MATLAB? Sounds like maybe it is still x86_64.

How can I identify the architecture for my MATLAB? I downloaded the R2024a version for macos from the mathworks website. I would be happy to switch to the Python-based one, I just don't know how to because the commands appear to only work for windows os

No clue - check out the MATLAB docs. Sometimes it is in the about page.

I use Mac as my primary OS, so the Python interface definitely works, and I have an M2.

I've now successfully managed to follow the steps for the MATLAB wrapper, but am now running into a new problem. I am trying to run a set of files built on REFPROP 9.1 and the old MATLAB wrapper (with the refpropm file). In order to get it working with the new wrapper, do I just need to replace every instance of refpropm with RP? Is there a specific place within my file setup that the downloaded files need to be saved in order to refer to the REFPROP library?

I can also open this as a new issue or change the header on the current issue if either is preferable for your organizational system.

Yes, that is right, you need to either write your own wrapper function to replace refpropm, or rewrite your code. Also, you should upgrade to version 10.0

There is also the refmatpy interface which is similar to refpropm: https://github.com/usnistgov/REFPROP-wrappers/tree/master/wrappers/MATLAB#refprop-for-matlab
