The EULER Software
Version 1.57

Deutsche
Einführung
Euler is a numerical laboratory with a programming language. The system can handle real, complex and interval
numbers, vectors and matrices. It can produce 2D/3D plots. Included is a modern programming language. All versions
are freeware under the GNU general license.
Highlights are
- real, complex and interval scalars and matrices,
- a programming language, with local variables, default values for parameters, variable parameter number, passing
of functions,
- two and three dimensional graphs,
- marker plots,
- density and contour plots,
- numerical integration and differentiation,
- statistical functions and tests,
- differential equations,
- interval methods with guaranteed inclusions,
- function minimizers (Brent, Nelder-Mean),
- Simplex algorithm,
- interpolation and approximation,
- finding roots of polynomials,
- calling of functions in external DLLs,
- sound playing,
- Fast Fourier transform (FFT),
- an exact scalar product using a long accumulator,
- New: Postscript graphics export (thanks to Eric Boucharé)
and lots more. The specials of the notebook versions (Windows, OS/2) are
- editable command window with comments,
- normal OS GUI,
- graphics export in various formats (WMF over the clipboard)
For more information you can view
You can get Euler in several versions
- Windows 95/98 Installer (also for NT).
This is a selfextracting and installing Windows executable. You simply run it to install Euler and set up the necessary
program icons in the start menu.
- Windows No-Install version. Simply
run euler95.exe to start the program. To remove it, delete the main directory and if necessary, the registry information.
I prepared this to show that direct usage from a CD-ROM is possible, and that Euler does not fiddle with your system.
Moreover this version is considerable shorter to download.
- Linux/Unix Version (still with a restricted
interface). This version needs to be compiled with any Ansi-C++ compiler (like Gnu C++). This version contains
the sources for all versions of Euler.
- Precompiled Linux Version.
- OS/2 Version (no longer maintained).
The source is available under the GNU
general license. The main point is that any modified versions remains freeware and open source, und must be distributed
with a clear reference to this original version.
