Re: [Matlab-emacs-discuss] error when running system command

[Ondra K. <ond...@gm...>]

Dear all,

the reported problem does not seem to concern matlab-shell at all. So my
email can be ignored here.

I found out the similar problem happens in 2018b but for legend command
when run in matlab-shell, and then I found out that this problem is also in
2018a if run from terminal. It does not depend on matlab-shell in emacs. It
seems to depend on the order i ran different versions of Matlab.

It rather seems that the problem might be connected with three Matlab
installations, so i will investigate. Maybe my ~/pathdef.m is not loading
all the paths because it gets overwritten by another matlab? Anyway, i
apologize for disturbing a wrong list.
