I'm sorry if this question has already been covered here, but I was
not aware of comp.dsp until this evening :-(

We are currently looking for a suitable software package for signal
acquisition and analysis on a PC platform in our biomagnetism lab.

We would like to use the programs for signal acquisition, data editing,
fairly advanced signal processing, control of analouge and digital I/O
and would most of all like to see this as a set of callable subroutines
to include in our own software.

After scanning most of the market (I think) we seems to be left with two
candidates: ASYST and MatLab-386.

None of these packages allow us to use then as a library, rather, we will
have to use these programs as our platform, calling special routines
of our own from them :-(.

Questions:
If you have used one or both of these programs, what is your general
opinion?

ASYST offers possibilities to create a good, graphics oriented, user
interface, but what about speed? Is it slow in signal processing/analysis
operations compared to MatLab? Benchmarks?

Programming MatLab seems to be quite straight forward, but ASYST's FORTH-
looking code makes me a bit doubtful. Do you write understandable, main-
tainable code in ASYST?

Can MatLab support mouse driven, menu/icon based user interfaces?

Any problems interfacing to routines written in e.g. MS-C 6.0, Turbo C++
or Fortran77 (probably Laheigh)?

Since we are planning to interface the software to a couple of hardware based
(TMS320C25) adaptive filters, it would be interesting to hear of any
such experiances.

If you respond directly by E-mail, I'll post a summary to the net provided
there is enough interest.

BTW - are there any listservers/mailservers on signal processing?
