do I need any compilers for MATLAB 2020b

I am running MATLAB 2020b on a MacBook Pro running the latest Mac OS ,

Do I need any C, C++, Fortran compilers and any X11 support ?

Walter, thank you very much for answering my question.

You do not need X11 support at all, not since quite a number of releases ago.

Compilers are not required to run basic MATLAB or Simulink, or the basic functions of most of the toolboxes.

Fortran is not generated by anything in MATLAB, so you only need a Fortran compiler if you intend to link to Fortran code or you intend to write mex routines in Fortran.

C or C++ compilers may be required if you intend to link mex routines, or if you intend to use MATLAB Compiler, MATLAB Compiler SDK, MATLAB Coder, Simulink Coder, or if you intend to generate code for a target such as a DSP. Compilers for some third party devices are loaded when you load appropriate support packages -- for example the Raspberry Pi loads in a compiler that is seperate from clang .
