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
Version 2.2, Build 1148 (62bfcca) Tue Jan 28 00:51:35 2020

Installation info:
Path: /Users/mingchengnie/CVX_Fold/cvx
MATLAB version: 23.2 (R2023b)
OS: Mac OS X aarch64 version 14.0
Java version: 1.8.0_392
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

And download a distribution targeted for your platform.

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.
