Hello François,
Now, on the other side, Rev has a very nice language, but non
existent support for, let us say, C style arrays of fixed size
double precision floats. What I mean is that variable typing somehow
is not really supported in transcript. In many cases this is a
blessing, but when you go for pure computing performances, it's too
bad.
Even at a low level stage (untyped vars are a traditional xtalk
facility but typed vars are probably available behind the scene as
undocumented features), is'nt Kevin, Mark W. ?.
I will take an example. Go to
http://www.macresearch.org/performance_tutorial_part_i_introducing_accelerate
and you will see that MacOS X included vector optimized of BLAS and
LAPACK (public domain numerical package for linear computations, for
those who are not in this field). Now, because of their history,
parameters must be passed using the FORTRAN conventions. I think
this can be done in the rev externals. However, I do no know if it
is possible to pass, say, a double float array from runrev.
Does someone got a tested way to do this from Rev ? Andre, Mark S. ?
If this could be done, this could be very beneficial to the
scientific (in the broad sense) community because the core of
matlab's routines could be ported to revolution, with the benefit of
having the wonderful rev environment.
If, in addition to this, externals based on the accelerate framework
could be used in the now free revmedia, this would be a tremendous
opportunity for the scientific community (especially in college) to
drop the pricey matlab in favor of revmedia.
Unfortunately, I am not geeky enough to do this by myself...
Nor i'm ... ... ;)
Best Regards,
