Hi,

I'm interested in Octave because I want = to port=20 algorithms coded in

Matlab, first to a platform with = a Mac=20 processor running Linux, then to an

embedded real-time processor. I = have=20 the Matlab Compiler, which generates=20

C code which in principle = could be compiled and run with the gnu C/C++ compiler =

under Linux; but the=20 code which the Matlab compiler generates requires libraries

of binaries which aren't available for = the Mac or=20 the embedded system.

Three questions:

1) According to your web page, Octave = can run=20 either interactively or noninteractively.

When it's running nonintereactively, = does it tend=20 to run more like interpreted code

(e.g., as slowly as uncompiled Matlab) = or more like=20 compiled C (e.g., like

Matlab MEX files)?

2) Does the distribution for Octave = consist=20 exclusively of source code; i.e., code which

would be portable to=20 any Unix/gnu C/C++ system?

3) When I transferred the downloaded = .gz file for=20 the stable version of Octave,

(from the FSF site as well as yours) = Viruscan=20 declared the file to be infected.

Subsequent re-scanning of the .gz file = sitting on=20 the disk said it was OK.

I assume the code itself is checked at = your end,=20 and the virus-alert was itself a bug,

but thought I should mention it (and = await your=20 reply before unzipping it!)

...Have others reported = problems like this?

Thanks,

Mark
