The vast majority of my code blocks do not use sessions but I don't use
matlab or octave. Running something like the following as part of the
session start up does seem reasonable.
(format "cd('%s');\n" default-directory)

The alternate (and probably simpler) solution here is to set the default
to whichever of .sh or .bat seems more likely to be desired based on the
OS, and then let the user customize the `org-babel-tangle-lang-exts' to
suite their preference.
