***************************************************************
General Words of Wisdom
from
Brian Evans'Signal Processing Packages
:Copyright: Copyright 1989-1991 by Brian L. Evans,
Georgia Tech Research Corporation.
***************************************************************
--> Macintosh Users
Please let Mathematica allocate as much memory as possible.
Conventional wisdom says 8Mb is adequate. You can check the value
by clicking once on the Mathematica icon and select the Get Info
option from the Finder's File menu. It is the number that appears
in the lower left-hand corner of the info window.
--> Warning
A warning about opening some Notebooks under Mathematica 2.0.
The new version of Mathematica changes the storage of PostScript
graphics. PostScript graphics are now stored WITH the 20 kb header that
was "assumed" to be there under Mathematica 1.2. When you open a 1.2
Notebook under 2.0, Mathematica will prepend this 20 kb to each
PostScript graphic and render the graphic. Therefore, those
Notebooks containing many graphics cells will take a long time to
open under Mathematica 2.0. It also means that Notebooks will grow in
size. Some of the signal processing Notebooks will quadruple in size,
thus overwhelming the machine.
--> Suggestion
Please, please, use lower case one-letter symbols as
variables and do not assign values to them. This includes variables
like n, t, x, and y, as well as t1, t2, etc. Use one-letter upper
case variables to represent constants (A, G,...), although Mathematica
reserves I and N and we reserve L and Z.
