into matlab-shell.

With :dir, should expand when :dir differs from current buffer dir

But not during export

gnuplot

Looks like gnuplot doesn’t respond to default-directory. I think that is because shell-command-to-string uses call-process instead of process-file. We may want to use shell-command-on-region or shell-command.
