Details:

MATLAB interprets plain ampersands and tildes in TeX strings as printable
characters whereas Octave expects them to be escaped as "\&" and "\~",
respectively.

Using either of them un-escaped in Octave causes weird output.

Plain ampersands and the character following them are replaced with a space in
Octave only. Example:


axes
title('abc&def&\gammahi')


This yields "abc ef hi". Notice how the second ampersand doesn't mask the next
byte (i.e. the backslash) but rather the next character sequence (i.e.
"\gamma").

Plain tildes in Octave make the following three characters superimposed on
each other. Example:


axes
title('abc~defghi')
