interactive mathematical programming environment

Euler is a powerful numerical laboratory with a programming language. The system can handle real, complex and interval numbers, vectors and matrices. It can produce 2D/3D plots.

Euler features among other things:

 * 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
 * animations
 * 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
 * fast Fourier transform (FFT)
 * an exact scalar product using a long accumulator
 * PostScript graphics export

This package contains the main program. Documentation for Euler is included in the euler-doc package.
