Signal Processing ftp server update

  • To: mathgroup at

     A version of the signal processing packages that is (finally)
fully compatible  with  Mathematica  2.0  (and still runs properly
under Mathematica 1.2) is on the Mma SIG ftp site.  The accompany-
ing Notebooks still contain graphics cells formatted under Mathe-
matica 1.2 so they will have to be re-rendered under Mma 2.0.

     The release is now available for different computers:
SigProc2.0.tar.Z          compressed tar file for Unix systems       zip file for the IBM PC running MS-DOS
SigProc2.0.mac.sea.hqx    binhexed self-extracting archive for Mac

    The current version of the release is 2.62.   Since  the  last
release (2.44), the transform rule bases have been "idiot-proofed" 
and they will display assumptions  made  on free parameters if the
Dialogue  option  is  All.  The user-specified transform pairs now
take precedence over the built-in onces.  The convolution routines
better handle infinite duration functions.   We've added a host of
factoring operations with integer matrices.  The plotting routines
SignalPlot,  SequencePlot,  and MagPhasePlot take the same options
as does Plot.  A "Master.m" file defines the entire release.
