Hi Gorazd,
Yes, you can call Fortran 95 code from Octave. You might want to take a look to
my optimal
interpolation module: http://ocgmod1.marine.usf.edu/OI/
In this implementation, I used two wrappers:
C++ wrapper
|
Fortran subroutine wrapper with explicit shape matrices (optiminterp_f77.f)
|
Fortran subroutine with assumed shape matrices (optimal_interpolation.F)
I don't know if there is any (portable) way to call Fortran subroutines from
C++ with assumed shape
directly. You would have to deal with low level the array descriptors with are
quite compiler dependent.
The Fortran 2003 standard ease the interoperability between Fortran and C (look
for the
ISO_C_BINDING module). It gives you some control, how the subroutine is named
in a object file (with
BIND). Unfortunately, few compiler implement this standard (g95 is a notable
exception). As far as I
know, the 2003 standard, don't let you call subroutines with assumed shape
arguments.
I would be interested to know if some one succeeds to use only one wrapper.
Since octave 2.9.9 (I think), mkoctfile recognizes free formated Fortran code
(with .f90 or .F90
file extension).
Regards,
Alex
