  I realize that you probably have been through this before, but if so I
missed the posting.  Could somebody please explain the available Mathematica
versions after 2.0 and their relationship with NeXT architectures/OS.
  The reason I ask is that I am currently using Mathematica 2.0 on a
NeXT running the 2.1 OS.  I have seen mentioned in this newsgroup
versions 2.0.4 and 2.1 and I would like to help our Computation Center
remain current.

Thank You

Subject: how to 'undo a Partition' ?
Date: 26 Jul 92 12:35:19 GMT

i'm going crazy(ier) using partition. here's what i'm looking at:  

starting with, for example:

mat = {{0, 0, 0, 0}, {0, 4, 4, 0}, {0, 2, 0, 0}, {0, 0, 0, 0}};


mat//MatrixForm
0   0   0   0

0   4   4   0

0   2   0   0

0   0   0   0

i  perform the following partition:

submats= Partition[mat,{3,3},{1,1}];
{{{{0, 0, 0}, {0, 4, 4}, {0, 2, 0}}, {{0, 0, 0}, {4, 4, 0}, {2, 0, 0}}}, 
 {{{0, 4, 4}, {0, 2, 0}, {0, 0, 0}}, {{4, 4, 0}, {2, 0, 0}, {0, 0, 0}}}}

submats//MatrixForm
0 0 0   0 0 0
0 4 4   4 4 0
0 2 0   2 0 0

0 4 4   4 4 0
0 2 0   2 0 0
0 0 0   0 0 0


the question is, if i'm going in the opposite direction, starting with 

submats = {{{{0, 0, 0}, {0, 4, 4}, {0, 2, 0}}, {{0, 0, 0}, {4, 4, 0}, {2,
0, 0}}}, 
                    {{{0, 4, 4}, {0, 2, 0}, {0, 0, 0}}, {{4, 4, 0}, {2, 0,
0}, {0, 0, 0}}}} 

how do i get 

 {{0, 0, 0, 0}, {0, 4, 4, 0}, {0, 2, 0, 0}, {0, 0, 0, 0}}

i need the general soluution

the general problem is this: 

what is XXX in

list = XXX[Partition[list,...]]

ie., how do you 'undo a Partition' ?

this would be useful if you had a list and wanted to modify the elements of
the list based on the sublists that you create from the list. sort of like 

newlist =  Unpartition[Map[Test, Partition[list,...] ] ]

thanks for any suggestions.

Try adding a PlotStyle specification to the definition of g2
For example:

	g2 = Plot[ f[2], {x,a3,b3}, PlotStyle -> Dashing[{.03}],
		DisplayFunction->Identity]

That did the trick under Mma 2.0 on my NeXT Cube.

I am new to using mathematica and so this simple question on getting hard
copies of graphics output from Mathematica. Since I am using Mathematica on
text based machines, I could use the Display funtion to download the graphics
into a postscript file. However, the book by Wolfram warns that it needs to
be changed before it can be printed out on a postscript printer and I wasn't
sure what all needs to be done before I could print it. Obviously, I tried to
print that file and it didn't work. Any help in this direction would be very
helpful. Thanx.

A recent article in sci.math indicates that Maple has a similar

Subject: Symbolic Algebra subroutine library?
Organization: California Institute of Technology, Pasadena, CA
Date: Fri, 24 Jul 1992 22:43:50 GMT


I would like to know if there is a symbolic algebra subroutine 
library suitable for linking to C/C++ programs.  More specifically,
I would like to use the algebraic manipulation capabilities of a
package like Mathematica (as just one example) available from
within a compiled and linked program.  For example, the program
might construct an expression like (a + b)(c + d) represented
internally in some data structure (maybe a tree, maybe just a 
string).  Then, a subroutine called with this expression as an
argument would perform an operation on the expression and return
the result in the same data structure type.  For example, a routine
called multiply might return ac + ad + bc + bd in the data structure.

After watching this news group for a few weeks, it appears most
symbolic work is done through front ends like that with Mathematica
or Maple.  Do either of these have an API (application programmer
interface) for accessing their functionality?

Some people have suggested shelling out a separate process to
run Mathematica and then parse the resulting output.  This is
not acceptable for a variety of reasons, not the least of which
are speed, portability, etc.  My program will be generating
hundreds of expressions, doing simplifications, and using the
results.  For now I have programmed the simple expression tree
simplifications myself, including some simple derivatives.  But
as the expressions the program creates become more complex, I
will not be able to compete/reproduce the functionality of
good symbolic algebra packages.  Therefore, I would like an API
to such a package!  Any suggestions?

You will find that it is not always clear what the simplest form of
a given expression is, after some obvious simplifications like
converting something+0 to something and something*1 to something.
The above is the standard reading on these issues.

If "roots" is of the form {{a_11,a_12,...a_1k},(a_21,a_22,...,a_2l},...}, set "trootlist" to
{{a_11,a_12,...a_1k,1},(a_21,a_22,...,a_2l,1},...}.

Note also that this is not good mathematica code;

trootlist = {Join[#,{1}]&) /@ roots

would be more understandable (to someone familiar with Mathematica).

Theorist has a great user interface.  Miles ahead of Maple or Mathematica.
The formulas you see on the screen look like real math.  Do computations
using mouse and menus.  For example, to solve an equation for x, grab the x
and drag it to the left side of the equation.  To substitute one formula
in another, grab it and drag it to where you want it substututed.

On the other hand, Theorist has only rudimentary programmability, a minimal
library.  Many, many, problems that Maple and Mathematica can do automatically
cannot be done (except by hand) using Theorist.  What would be ideal would
be the Theories interface on the Maple libraries.  But I do not see it coming
soon. I have (and frequently use) both Theorist and Maple.

Much superior to the interface on line-oriented terminal computers.  Uses
a "notebook" metaphor, like Mathematica.  Cut and paste formulas.
Go back and edit a mistaken entry.  There now exist Sun and NeXT
versions of Maple with similar capabilities.
