Hi, Peter
Thanks for the comments. I have been prototyping my numerical routines
in Matlab and have encountered parts of algorithms that don't lend
themselves to vectorization. So, I am "forced" to use loops, any of which
Matlab executes slowly at best. Fortran has gone .Net, which (without being
to far off the mark) is yet another byte-compile-then-interpret strategy and
is therefore slow at loops (yes, above all, floating point operations, but
also integer, string, and whichever other ops-in-a-loop as well). Do you
know of a Delphi component that allows run-time execution of Delphi source
code or compilation as a DLL for subsequent incorporation into a running
program (if Windows XP allows such stunts). In other words, is there a way
of taking the relative-runtime advantages of Delphi compared to Matlab,
Java, and VB, splicing them with the advantages for problem-solving of
Matlab or some interpreted and conditionally byte compiled enviroment and
hone in on performance bottlenecks replacing them with inline assembler code
behind the scenes by some profiling on the fly means just for the purposes
of testing, not final release?
Cheers,
Paule
