EULER

Copyright by R. Grothmann

This is EULER, the numerical software. The program started as a MatLab
clone on my Atari ST. There are now versions for UNIX, OS/2 and
Windows 95. The UNIX version is a bit behind in the user interface. If
you have OS/2 or Windows 95, try one of those. If I find the time, I
will improve the UNIX interface. The OS/2 version is no longer
maintained.

To make Euler on Linux, go to the source subdirectory, and type
	make install
The make file is ready for Linux with Gnu C compiler. The target
xeuler will be copied to euler/progs. There is a shell script euler,
which starts the program. There is also a version noxeuler, which is
command line oriented.

For a quick overview over EULER, start the program and type
	>load "demo"
The documentation is provided via an HTML file in docs/euler.html. You
may find examples in docs/examples.html. There is an online help
available with the help command
	>help
There is also an manual page available in docs/xeuler.man. Copy this
as xeuler.1 to your /usr/man/man1 directory, and gzip it there, using
root priviledges, if you like.

Features of EULER are a numerical matrix language with reals, complex
numbers and intervals, two- and threedimensional graphics, and a
programming language. The program contains several problem solvers,
like numerical integration, differentiation, root finders and solvers
for differential equations. It can compute the basic statistical
distributions and generate random numbers.

The command line options accepted by EULER are
	-f font			sets the text font
	-g font			sets the graphics font
	-s Kbytes		sets the available space
	-geom geometry	sets the window geometry (e.g., -geom 600x600+0+0)
	-d display		sets the display
	-## color		sets color ## (0 to 15) to the color name
					(e.g. -0 LightGray for the background color)
	-b              uses a black and white color scheme
	-x              catch FPE and abort execution
	files			are files to be loaded after EULER.CFG
