AXIOM Release 2.0a
As well as a number of enhancements and bug-fixes to the algebraic libraries, AXIOM Release 2.0a incorporates three major changes to
the AXIOM system:
- Introduction of a new patch facility: this will allow users (and NAG) to keep track of future bug-fixes and enhancements
applied to AXIOM from materials distributed electronically. via the WWW. or by more traditional means.
- Reorganisation of the link to the NAG library: to save space the interfaces have been grouped together into packages, so that
where previously the routine c05adf was implemented in c05adfPackage, it is now implemented in NagRootFindingPackage
(abbreviated NAGC05) along with all other NAG routines whose name begins ``c05''. Users may need to recompile code
which uses the NAG link.
- A large number of improvements have been made to the axiomxl compiler: in particular, compilation is now faster and
executables are now smaller, and there have been a number of improvements to the optimiser. AXIOM code compiled with
earlier versions of the compiler will need to be recompiled because of improvements to the runtime system.
PC Macsyma 2.0 and Unix Macsyma 419
PC Macsyma(R) 2.0 marks the second generation of math software. The major
new features are summarized below.
Notebook Interface
Notebooks combine math, text, and graphics in one document.
- Math display: Output expressions (and echoed input if desired) appear
with textbook quality display, including math symbols, Greek
letters. Special formatting methods make large expressions easier
to read at a glance. You can make large math expressions appear in
sections which scroll horizontally and/or vertically. You can select
most formatted math output with a mouse and resubmit it as input.
- Graphics editing and display: In a typical 3D graph, you can edit
over 200 attributes right in the notebook, using five custom dialog
boxes and context-sensitive toolbars.
- Text processing: Format individual characters (font type and size,
bold, italics, underline, color) paragraphs (left-right-first-line
indent, left-center-right alignment, vertical spacing inside and
between paragraphs, tabs), and pages (margins, page breaks,
headers, footers).
- Hypertext links (starting with Macsyma 2.0.8): includes user-defined
hypertext links within and between notebooks. Links can target
closed notebooks in different directories.
- Navigate dialog (starting with Macsyma 2.0.8): contains a short
summary or assigned names of sections in a notebook or notebooks.
It can be used to present an outline of the notebook. Users can
jump to any section displayed in the dialog.
The hypertext links and Navigate dialog enable you to seamlessly link
very large documents consisting of dozens of notebooks.
Graphics Macsyma 2.0 has object-oriented graphics with camera animation, data
animation and clipping planes.
- A typical 3D plot has over 200 editable attributes, which can be
edited in the notebooks with five custom dialog boxes.
- Publication quality labeling
- IHS and RGB color models, spot and flood lighting
- Adjust viewpoint, roll, truck, zoom
- Interactive query for coordinates
The product comes with an animated movie of a safari through the
inside of a Klein bottle. (You do survive and come out ''the
other end''.)
Linear Algebra Macsyma 2.0 has more symbolic-numerical linear algebra than any other
product, and almost as much numerical linear algebra as specialized
numerical products.
- 180 new matrix commands, including SVD, Schur form, and many other
operations.
- Language extensions for compactly specifying matrix operations,
using a Matlab-like syntax.
- A Matlab-to-Macsyma translator. Translate Matlab(TM) function files
into Macsyma command files, load Matlab files directly into
Macsyma, or type Matlab commands into Macsyma.
Numerical Analysis Macsyma 2.0 has many new features in numerical analysis.
- Numerical integration: a new extrapolated Gaussian quadrature
package called QUADRATR.
- Differential equations: ODE_STIFFSYS solves stiff systems of
O.D.E.s. See P.D.E.s below.
- Data fitting: nonlinear multivariate least squares fits of
data. More descriptive statistics.
Partial Differential Equations Macsyma can find symbolic symmetries and solutions of systems of
P.D.E.s. It has new capabilities to generate symbolic P.D.E.s in
arbitrary coordinates. The companion product PDEase(R) solves
P.D.E.s numerically using finite element analysis.
Symbolic Integration Macsyma 2.0 has improved symbolic integration, for integrals involving
error functions, incomplete gamma integrals, and more elliptic
integrals. A new implementation of the transcendental Risch
algorithm is faster and more powerful.
Documentation The Macsyma Reference Manual (15th edition) and the Macsyma User's
Guide (second edition) and the on-line help document the new
features in Macsyma 2.0. Hypertext help is context-sensitive:
Place your cursor on a word, and the F1 key sends you directly to
the description of that word. German language versions of the main
on-line documention are available.
PC Macsyma 2.0 is available for the Windows 3.1 or 3.11, Windows 95
and Windows NT 3.5 or 3.5.1 operating systems. Macsyma 419 for
UNIX workstations includes the same math engine as PC Macsyma 2.0,
without some of the notebook and graphics features.

Maple V Release 4
Shipping in the winter of 1995, this release will provide significant
enhancements to all dimensions of Maple --- graphical user interface,
plotting, symbolic computation, numeric computation, and the Maple
language itself.
One of the most important areas of improvement is in the graphical
user interface for preparation of Mathematical documents. Release 4
includes an enhanced worksheet model with outlining controls,
stylesheet-based document formatting and display facilities, and
in-line display and manipulation of Maple graphics.
REDUCE 3.6
Version 3.6 of REDUCE is now available for distribution. This is the first major update since the release
of REDUCE 3.5 in October 1993. As is usual for a new release, a large number of bugs and awkward
features (including those documented in the patches.red available from the REDUCE Network Library)
have been corrected. Taken together with the many new features that have been added, REDUCE 3.6
represents a significant enhancement over previous versions.
In addition to the capabilities of the original release of REDUCE 3.5, this new version supports, among other things:
- definite integration
- noncommutative Gr”bner bases
- expanded special function handling
- improved solve capabilities
- improved trigonometric simplification
- linear algebra and linear programming
- matrix normal forms
- operations on sets
- residue computations.
The REDUCE algebraic mode has been improved substantially since the last release, in particular it offers:
- improved rule list capabilites, including free operators, conditional binding of variables and better match facilities e.g. for quotients
- a new trace module allows the trace on algebraic level which includes a trace facility for rule lists.
The REDUCE graphic interface has been improved e.g. the user is now able to plot implicitly defined functions.
