[EvA] matlab interface

[M.Kronfeld]

Hi there,

the Matlab script 'testfun' actually implements a whole set of specific
test functions. Therefore it expects an additional integer flag
parameter (the 'y') which desides on which specific function to employ.
The parameter may be given when instantiating the JEInterface as the 4th
argument (after R). Take a look at testfun.m to find out which functions
are available. The JEInterface parameters are also described in the
Matlab console help text.

Best regards,
 Marcel
