In Matlab 5.* one has the possibility to include several functions in the
same file, although the scope is limited to that file (i.e. the function is
not callable from outside that source file). If you look towards the end of
spm_extract.m you will find the definitions of the "puzzling" functions.

Check the help for "isfinite", for which finite is a short.
