Ran in:
I have to use this line of code which is supposed to generate the image of a graph using GraphViz (which is installed correctly as using the same line on the terminal works):
system('dot -Tpng graph.gv -o Graph.png');
/bin/bash: dot: command not found
but i get the error:
zsh:1: command not found: dot
Is there a way to make it work without using the GraphVIz add on?

Hello,
'system' starts a new shell process which may not inherit your familiar environment.
I suggest you check the PATH in matlab by
getenv('PATH')
and then try to add some needed paths by setenv, such as
setenv("PATH", [getenv("PATH") ":" "where_is_the_dot_command"]);
