From: Waldek Hebisch on
FriCAS is an advanced computer algebra system. Its capabilities range
from
calculus (integration and differentiation) to abstract algebra. It can
plot functions and has integrated help system.

FriCAS 1.1.0 builds on Linux, many Unix like systems (for
example Mac OSX and Solaris 10) and Windows.

FriCAS is build on top of Common Lisp; several Lisps can compile
and run FriCAS -- currently supported are GCL, SBCL, Clisp, ECL,
Closure CL (former OpenMCL) and CMU CL.

Notable changes (compared to version 1.0.9) include:

- New domains and packages: VectorSpaceBasis domain,
DirichletRing domain, 3D graphic output in Wavefront .obj format,
specialized machine precision numeric vectors and matrices (faster
then general vectors and matrices), Html output.

- Support Clifford algebras corresponding to non-diagonal matrix,
added new operations.

- 'normalize' now tries to simplify logarithms of algebraic constants.

- New functions: Fresnel integrals, carmichaelLambda.

- Speed improvements: several polynomial operations are faster,
faster multiplication in Ore algebras, faster computation of
strong generating set for permutation groups, faster coercions.

- Several improvements to the guessing package (in particular new
option Somos for restricting attention to Somos-like
sequences

Bug fixes, in particular:

- FriCAS can now compute multiplicative inverse of a power series
with constant term not equal to 1.

- Fixed a problem with passing interpreter functions to algebra.

- Two bugs causing crashes in HyperDoc interface are fixed.

- FriCAS now ignores sign when deciding if number is prime.

- A failing coercion that used to crash FriCAS is now detected.

- 'has' test sometimes gave wrong result.

- Plotting fixes.
