Hello,

have you taken a look at tikz-qtree? It makes tree building slightly easier and allows e.g. lines between nodes. The tikz-qtree manual on page 6 shows something remotely similar to what you want to do.

If all fails, draw it manually in Inkscape?

Best wishes

If you are using TeXnicCenter, you can try this. Using other editors, that link still may give you some hints how to do it.

You can change the encoding of your m-file.
Open it in an editor (e.g. Notepad++) and then save the file anew, with a different encoding. ANSI should work.

Potential warning: I don't know, how Matlab will react, when it tries to use that m-file and it is not utf8 encoded

Have you checked that Polish for your TeX system is installed?

Someone had a similar problem with Spanish.
