Just to add my 2 cents to the discussion and in order to be brief, I
support completely the opinion of Michael Hanke posted just before.
Prior to moving to the Linux/Octave world I worked with Matlab,
Mathematica and Maple under Windows. Full inclusion of symbolic math
in Octave will result in a much bigger and slower code. Also, syntax
should change dramatically. When I tried to do numerical computations
in Maple or Mathematica they resulted in much longer scripts than in
Matlab. The solution of having some kind of interaction between Octave
and an external symbolic package seems appealing and much more in the
"Unix spirit".
On the other hand, I'm very interested in having sparse support. Right
now, I'm using a Fortran skyline solver that I run externally and use
"popen2" to pipe results from and to the Fortran code. It works
reasonably well but I wish to write a .oct file. However I'm new to
C++ and I didn't found a simple example (like oregonator.cc) in
Fortran. I looked at some of the Fortran packages like lsode, etc...
but I didn't understand fully the mechanism of making .oct files from
Fortran.
Regards,
Mario
