Conference hydra::amiga_v1

	I'm interestd. Also does anyone (or this file for that matter)
	have any ANALOG SIMULATORS for the Amiga?

	I'm interested in a Spice-like simulator...Or alternatively,
	if someone has sources I have a C compiler...

	Ed A.

    I'm interested too.  Being still in school, I need to use Matrices
    almost every day.  I'd also be interested in a spice-like system
    for the Amiga.  Any packages out there for circuit Analysis?  I
    have something for the I*M called Micro-Cap II, but it won't run
    on the Amiga.  It's a really nice graphically oriented system (IE,
    no programming languages for circuit construction)  If there's
    something out there similar to that, it would be nice.

    I think I have a small modal analysis (electrical or mechanical)
    program called SNAP (Simple Nodal Analysis Program).  This one had
    an Intuition front end, but I never really played with it very much.
    
    I do have a program written in Basic that solves for the forced
    response of undamped multi-degree-of-freedom systems given the
    masses, spring rates, and forcing function magnitude and frequency.
    It only handles sinusoidal inputs (step response is a whole lot
    tougher).
    
    Ed.                                  
    

    Can I get you to upload SNAP for me?

	Another vote for uploading the matrix software.

    
    Glad to see some masochistic engineering types here...
    
    I believe I'll upload to martin Ellis' RA81.  I'll first post the
    files (MATLAB.ZOO, MATLABDOcS.ARC, SNAP.ARC) to
    
    	NORSE""::AMIGA:[UPLOAD]
    
    I'll then send Martin e-mail asking that the files be moved to
    
    	NORSE""::AMIGA:[UTILITIES] 
                       
    I expect I'll have everything uploaded by Saturday 11/12/88.  The
    next few nights are booked.

    For those willing to slog through the conversion process, Matlab
    appeared a few days ago on Usenet.  See recent notes in
    MSBIS::AMIGA_USENET if interested.

    Thanks Ed,

    Speaking of SPICE, I found what appears to be a working binary of
    an older version of PSPICE on a local bbs that I will upload if
    someone will tell me where I can copy it to.
    
    I haven't used it much yet (no time etc.), but it appears to be
    complete.

    Thanks to a female-only party that my wife attended (which featured a
    male stripper) I found that I had quite a bit of free time on my hands
    last night.  I completed the uploading of MATLAB.ZOO, MATLABDOCS.ARC,
    and SNAP.ARC to NORSE""::AMIGA[UPLOAD]. 
    
    As soon as Martin approves the uploads, they're yours for the asking.
    
    Ed.

    I have the source code for the PD version of MATLAB if anyone is
    interested.  Most of the code is in "vanilla" FORTRAN, except for
    a system-dependent file which contains routines for screen and file I/O,
    graphics, etc.  There are system files for some popular OSes such as VMS
    and Unix (I made a quick-and-dirty MS-DOS version too).  I've compiled it 
    under VMS and MS-DOS and it works great!  The installation manual describes
    what the files do, and how create overlays for computers with small
    memories.

    Any takers?

    Bill
    

    re .9
    	Try uploading to the same place that Ed is.  I'm sure he'll
    be happy to help you with anything unfamiliar.  I'm really eagar
    to get PSPICE.
    
     - Chris
    

	Another PSPICE vote here!

	Ed

    
    I have uploaded PSPICE.ZOO to NORSE""::AMIGA:[UPLOAD]
    
    It has all the Documentation etc with it, but it doesn't have any
    examples with it.  Someone may want to upload some of the *.INP
    files from another version of SPICE.
    
    Mark Mackelprang
    
    

	Yea!

    I have uploaded the VMS version of MATLAB (including source) in
    the directory PARITY::USER$04:[MUTH.MATLAB.VMS].  Relavent files
    include:

	INSTALL.      installation instructions 1100 lines 
	MAT.FOR       source code for MATLAB subroutine 3850 lines 
	LIB.FOR       source library 3339 lines 
	SYS_UNIX.FOR  Unix system-dependent code 900 lines 
	SYS_VMS.FOR   VMS system-dependent code 260 lines 
	MATLAB.DOC    full manual in original form 3960 lines 
	HELP.LIS      help text 700 lines (place in directory $MATLAB)
	DEMO.         eigenvalue sensitivity example 21 lines 
	MATZ.FOR      MATZ 100 lines 
	MATLAB.NROFF  NROFF input for manual 3250 lines 
	MAT.SNGL      single precision MATLAB subroutine 3850 lines 
	LIB.SNGL      single precision library source 3339 lines 
	MATLAB.EXE    executable files 

    The documentation (MATLAB.DOC) should be PRINTed using the
    /NOFEED qualifier.  Also, the logical name $MATLAB should
    be defined as the directory where HELP.LIS may be found.
    (the program will crash if $MATLAB is not defined).

    In summary, to get a running version of MATLAB, use the following:

    $copy parity::user$04:[muth.matlab.vms]matlab.exe []
    $copy parity::user$04:[muth.matlab.vms]help.lis []
    $define $matlab directory_where_HELP.LIS_is_located
    $run matlab

	Hi,

	Is there any chance of re-posting PSPICE? I copied the .ZOO file
	in November but hadn't had the time to upload it until this past
	weekend. Anyway after much wasted time the file wouldn't de-ZOO.

	The .ZOO file on my VAX had 2 RMS errors...

	Ed

The analysis uncovered 2 errors.

Are you by chance on a LAVC?  I've seen a similar error before.  Try simply
copying the file and ANALYZE the new copy.

    A new version of MATLAB came in today, but I only got 8 of the 9
    parts from comp.binaries.amiga.  You may want to spend your time
    on this latest version instead.

    Chong.

I'm on   a   CI   cluster.  It's  not  MATLAB  which  has  the  problem  but
PSPICE...Still no luck...Ed

    There's a PSPICE.ZOO in NORSE::AMIGA:[UTILITIES], if that's any help.

    - Z

    tried to get pspice from NORSE, no luck.  Can anyone help?  
    
    Thanks,
    
    John

    got it, thanks, John

	John, have you gotten PSPICE to work? 

	Everytime I try to copy it from NORSE (with either COPY
	or FTSV) I get RMS errors when I do an ANAL/ERROR.

	Is this expected?

	There is another SPICE, ASPICE, on FF177 but it requires
	1.5M. I'm running with 1/2 Meg. :-( [actually its my
	brother-in-law's machine so don't tell ME to upgrade]

	Thanx again to the fine human being who uploaded MATLAB!

	Ed

    
    I realize you can't use Aspice but I just thought I'd mention that a
    while back I ran a few circuits through HSPICE on the VAX and then ran
    the same decks (unmodified) through Aspice and the results were the
    same to within 2-3 significant figures.  Of course a 10 sec run on the
    VAX took 15 minutes on my generic 7.16 Mhz Amiga, but that is to be
    expected... 
    
    - steve mcafee

	The SPICE is for my brother-in-law. He doesn't have
	access to it on a VAX. But thanks for the figures.

	BTW: 10 CPU seconds of what VAX type?

	Ed

    re: -1
    
    It was 9.7 cpu seconds on an VAX 8650.
           920 seconds on a Amiga 1000 (Real time, but I set the priority
               up high so it had the full attention of the machine.  Mouse
               wouldn't even move...)
