How to use a command for the terminal which isn't a standard one?

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"]);
