    9   Is A Computer algebra system. The system has been designed by <name|Bernard
   10   Parisse> and is under active development. It is a general-purpose
   11   computation kernel written in <abbr|C++> with the following features.
   12 
   13   <\description-dash>
   14     <item*|Algebra>Arbitrary precision integers, integer and polynomial
   15     arithmetic, Gröbner bases, simplification, equation solver, partial
   16     fraction decomposition, linear algebra (vectors, matrices, row reduction
   17     to echelon form, eigenvalues and eigenvectors), permutations,
   18     combinatorial analysis, computing in <math|\<bbb-Z\>/p*\<bbb-Z\>> and
   19     <math|\<bbb-Z\>/p*\<bbb-Z\><around*|[|x|]>>
   20 
   21     <item*|Calculus>Derivatives, integration, limits, series expansion,

   35     variables, efficient sampling, maximum-likelihood fitting, statistical
   36     tests, kernel density estimation
   37 
   38     <item*|Signal processing and audio tools>Convolution, (auto)correlation,
   39     continuous/fast Fourier transform, Fourier series, filtering, windowing,
   40     loading, creating and saving audio clips, audio playback, resampling,

   44     global extrema, nonlinear programming, transportation problem
   45 
   46     <item*|Graph theory>Creating (random) graphs and digraphs, operations on

   60   <name|Giac> output is rendered in <TeXmacs> from its Scheme tree
   61   representation, which results in semantically correct formulas which can be
   62   copied back to <name|Giac>. Interactive plotting and mathematical input are
   63   supported as well.
   64 
   65   <paragraph|A note on session plots.>Any interactive <name|Giac> figure can
   66   be automatically embedded into the <TeXmacs> document by pressing \POK\Q.
   67   However, the PostScript conversion requires <scm|eps2eps> script to be
   68   available in PATH, which is resolved by installing Ghostscript. In
   69   <abbr|MS> Windows, paths to <scm|bin> and <scm|lib> folders in the
   70   Ghostscript installation directory (e.g.<nbsp><scm|C:\\Program
   71   Files\\gs\\gs9.53.3\\bin> and also <scm|lib>) must be manually added to the
   72   PATH variable after installation (type <verbatim|env> in the Start menu to
   73   edit environment variables).
