MATLAB environment variables issue with MacTeX 2020

Hello

I'm running several matlab script include using xelatex to compile LaTex code and export to pdf. I downloaded c from the official website and installed successfully, but I keep having this error when I run my script. I use Mac system in MacOS High Sierra and the code was run locally using matlab2020

/bin/bash: xelatex: command not found
...
LaTeX compilation failed.

I searched for lots of answers, the one I found the most useful is this one: https://www.mathworks.com/matlabcentral/answers/850-matlab-environment-variables

I used the suggestion from the answer to set :

setenv([getenv('PATH') ':/usr/texbin']);
setenv([getenv('PATH') ':/usr/local/bin']);

also

setenv('PATH', [getenv('PATH') '::/usr/local/bin']);

then I thought the installation path for MacTeX 2020 might changed, I found this: "The default installation directory is /usr/local/texlive/2020 on Unix"

after change the path and run this

setenv('PATH', [getenv('PATH') ':/usr/local/texlive/2020/']);

Still does not work and the same error showed up

Does anyone know how to fix this? Thanks!

https://www.mathworks.com/matlabcentral/answers/358850-matlab-external-scripts-can-not-escape-shell shows a quite different location.

The one from http://www.texts.io/support/0001/ installs into /Library/TeX/texbin/xelatex

Thanks for the reply! I did find the installation in /Library/TeX/texbin/xelatex as you mentioned, but the code itself still does not run, and below is the code that has been giving me trouble, I expect status = 0, but even I ran this

setenv('PATH', [getenv('PATH') '/Library/TeX/texbin/xelatex']);

%% Use pdflatex to generate the pdf
switch latex_compiler
    case 'pdflatex'
        cmd = ['pdflatex --interaction=nonstopmode ', fname, '.tex'];
    case 'xelatex'
        cmd = ['xelatex --interaction=nonstopmode ', fname, '.tex'];
    otherwise
        error('latex:compiler', 'Unknown LaTeX compiler.')
end 
status = system(cmd);
if status ~= 0
    error('latex:compile', 'LaTeX compilation failed.')
end

I still got status = 127 and /bin/bash: xelatex: command not found

I also tried this

cmd = ['/Library/TeX/texbin/xelatex --interaction=nonstopmode ', fname, '.tex'];
status = system(cmd);

I got status = 1 and /bin/bash: xelatex: command not found

Is there anyway to fix this? to get system = 0

/Library/TeX/texbin/xelatex is the fully qualified path of the executable, not just the directory name. So you should be using

setenv('PATH', [getenv('PATH') '/Library/TeX/texbin']);

Thanks! With this combination it worked!

setenv('PATH', [getenv('PATH') '/Library/TeX/texbin']);
switch latex_compiler
    case 'pdflatex'
        cmd = ['/Library/TeX/texbin/pdflatex --interaction=nonstopmode ', fname, '.tex'];
    case 'xelatex'
        %cmd = ['/Library/TeX/texbin/xelatex --shell-escape ', fname, '.tex'];
        cmd = ['/Library/TeX/texbin/xelatex --interaction=nonstopmode ', fname, '.tex'];
    otherwise
        error('latex:compiler', 'Unknown LaTeX compiler.')
end 
status = system(cmd);
if status ~= 0
    error('latex:compile', 'LaTeX compilation failed.')
end
