******************************************************************************
Laplace is now available to different CPU types. To install Laplace, use
need the archive
LaplaceBase.lha
and at least one of
Laplace000.lha
Laplace020.lha
Laplace020fp.lha
Laplace040.lha
depending of your CPU. Depack these archives into the same directory (e.g.
'RAM:') and start the installer script.
******************************************************************************
******************************************************************************
You need MUI3.3+ and the Installer V43.3. Download them now, if you don't
have them already.
MUI -> util/libs/mui39usr.lha
Installer -> util/misc/Installer43_3.lha

Laplace is now SHAREWARE!!
Although it is still a beta version, I decided to start with a lower price
than I planned. When Laplace gets some more powerful features (like a function
plotter), this price will increase. But if you register now, you won't have to
pay the difference!! I will start with 20DM or US$15. See the documentation
for more details.

Description:
Laplace is (or at least should be) an universal tool for mathematical
calculations. It lacks such a GUI with hundreds of windows like those
other progs I've found on AMIGA.
Instead it works like a shell, you enter a command and get the
result displayed, which is much more flexible.
This is just a beta version!!
There WILL be much more implemented, but I need YOUR support and
suggestions!!!!
Features:
· Basic two dimensional plotter and animated plots.
· Export graphs as PS or EPS.
· Works fully symbolic.
· Most basic complex, vector and matrix operations.
· Basic statistical operations on sets.
· Full derivation of functions.
· Numerical integration.
· Export formulas to LaTeX.
· Nice GUI, almost everything is configureable.
· Offers a revolutionary way of handling experimental results with
errors using gaussian error distribution.
· Localized, currently english and german.
· Full featured installer script.
· Documentation in AmigaGuide.
· Procedures and simple programming features.
Requirements:
· CPU: 68000 or better (no FPU needed)
· OS: 3.0 or better
· MUI: 3.3
· MEM: much, 4MB should be minimum
Changes since V0.12:
· 8.4.1998:
· ß1: Bugfix: redrawing wath screwed up with asynchron
calculation.
· ß2: Plotter: First simple PS export.
· 12.4.1998:
· ß3: Plotter: PS and EPS export works fine.
· ß4: Plotter: Added axis labels and legend.
· 13.4.1998:
· ß5: Plotter: Now displays e.g 2*10 ^ 2 instead of 2e2 .
· ß6: Manual: New appendix Future plans.
· ß7: Plotter: Axis number were place incorrectly with log
scale.
· ß8: Plotter: GhostScript (if installed) can now directly
be invoked to print PS files.
· ß9: : Plotter: Preview using GhostScript implemented.
· 16.4.1998:
· ß10: : Plotter: New (adaptive) handling of function's
precision.
· ß11: : Plotter: More flexible handling of axises.
· 17.4.1998:
· ß12: : Bugfix: Expressions like 1 + 2x caused a crash.
Reported by ??.
· 18.4.1998:
· ß13: New internal representation of displayed objects.
Uses less code and prepares Laplace for a possible PPC
port.
· 19.4.1998:
· ß14: Plotter: You can abort a zoom operation by pressing
the spacebar while the left mouse button is pressed.
· 20.4.1998:
· ß15: Plotter: Fixed some problems with logarithmic scale.
· ß16: Plotter: The window is not activated, if opened by
plot_open() . Suggested by Christoph Rickers.
· ß17: Button images are now loaded before the window
contents are drawn. Looks more professional according to
Christoph Rickers...
· 29.4.1998:
· ß18: Plotter: you can now change the fonts.
· ß19: Prefs: Use listview instead of register.
· ß20: About: New page Modules.
· 9.5.1998:
· ß21: Some modifications of the GUI (image buttons, etc.).
· ß22: Reimplemented online help system.
· 11.5.1998:
· ß23: Uff, what a day. Once again, my address has changed!
Now it's
Scheffelstraße 14
69214 Eppelheim
Germany
· ß24: Bugfix: Derivation of a ^ c, c=const was wrong
(c*a ^ (c-1) instead of c*a ^ (c-1)*derive (a,x) ).
Reported by Markus Mannevaara.
· 16.5.1998:
· ß25: After logically splitting Laplace into the
mathmatical kernel and the graphical interface, these two
parts are now physically seperated into two programs that
communicate via messages. In theory the kernal can now be
compiled for and run on a PPC while the GUI uses the 68k
processor. If you have a PPC card, you are programming
with the ppc-gcc and you would like to port the kernel to
PPC, please contact me!
· 14.7.1998:
· ß26: Bugfix: derivation of constants (pi, e) caused
Enforcer hit. Reported by Tommy Lindgren.
· 15.7.1998:
· ß27: Implemented Line archive and Color archive for
easier line and color definition.
· 30.7.1998:
· ß28: Bugfix: custom MUI classes where disposed before all
MUI objects where disposed, which could sometimes lead
into a crash at the exit of Laplace.
· 29.9.1998:
Finally it's out.
Notes:
German documentation is still incomplete. It's currently a wild
mixture of german and english parts.
