Branch: CURRENT, Version: 1.61nb45, Package name: euler-1.61nb45, Maintainer: pkgsrc-users

EULER is a program for quickly and interactively computing with real
and complex numbers and matrices, or with intervals, in the style of
MatLab, Octave,... It can draw and animate your functions in two and
three dimensions.

Euler features :
* 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
