CVX install on Matlab 2023b (Apple Silicon)

Hi, I have download the new version of Matlab natively support for Apple Silicon, i.e., 2023b for Apple Silicon. However, it seems I cannot install a CVX. Specifically, when I run 'cvx_setup', I have the following error report.

---------------------------------------------------------------------------

CVX: Software for Disciplined Convex Programming (c)2014 CVX Research

Verfying CVX directory contents:

WARNING: The following files/directories are missing:

/Users/mingchengnie/CVX_Fold/cvx/sedumi/.travis.yml

These omissions may prevent CVX from operating properly.

ERROR: one or more MEX files for this platform are missing.

These files end in the suffix ".mexmaca64". CVX will not operate

without these files. Please visit

Anyone has the same issue or is there any solution to solve it?

Hi Mingchen,

I understand from your query that you are not able to install CVX for MATLAB on a Mac with an Apple chip.

This is because CVX does not have MEX functions which are compatible with MATLAB for Apple Silicon.

To use CVX for MATLAB on a Mac with a Silicon chip, the following can be done:

• Install Rosetta, which allows applications compiled for Intel-based Macs to run on Apple Silicon-based Macs.
• Install CVX for Intel-based Macs.
• Use this on MATLAB for Intel-based Macs.

Hope this helps.
