Exciting latex file using Matlab giving errors

I have the following code

setenv('PATH', [getenv('PATH') ':/Library/TeX/texbin/pdflatex']);
setenv('PATH', [getenv('PATH') ':/X/Y/Documents/L.tex']);
command = 'pdflatex /X/Y/Documents/L.tex';
[status,cmdout] = system(command)

and I'm getting the following error

status =

   127


cmdout =

    'zsh:1: command not found: pdflatex

I got the path of /Library/TeX/texbin/pdflatex from typing "which pdflatex" using the terminal.

Any idea why I'm getting this error

Yes.

The system function uses a shell program and spawns a new process in which the command is executed; hence, the environment seen in the new shell is brand new and environment settings from the executing shell in which MATLAB is running are not inherited/seen in the new shell.

You can set environment variables by executing chained commands or using batch file that does the needed background work before launching the executable.

There's more info at system in the "More About" section.
