Notable changes in FriCAS 1.1.8 (compared to version 1.1.7): - Improvements of pattern matching integrator, it can now integrate in terms of Fresnel integrals and better handles integrals in terms of Si and Ci. - Better integration of symbolic derivatives. - Better normalization of Liouvillian functions. - New package for computing limits using Gruntz algorithm. - Faster removal of roots from denominators. - New domains for mutivariate Ore algebras and partial differential operators. - New package for noncommutative Groebner bases. - New domain for univariate power series with arbitrary exponents. - New special functions: Shi and Chi. - New package for noncommutative Groebner bases. - New domain for univariate power series with arbitrary exponents. - New special functions: Shi and Chi. - Several aggregates (in particular tables) allow more general parameter types. - New domain for hash tables using equality from underlying domain. Bug fixes, in particular: - Fixed problem with gcd failing due to bad reduction. - Fixed series of 'acot' and Puiseux series of several special functions. - Fixed wrong factorization of differential operators. - Fixed build problem on recent Mac OS X. Notable changes in FriCAS 1.1.7 (compared to version 1.1.6): - Improved integration in terms of special functions. - Updated new graphics framework and graph theory package. - Added routines for numerical evaluation of several special functions. - Added modular method for computing polynomial gcd over algebraic extensions. - Derivatives of fresnelC and fresnelS are changed to agree with established convention. - When printing floats groups of digits are now separated by underscores (previously were separated by spaces). - Added C code for removing directories, this speeds up full build and should avoid build problems on Mac OSX. Bug fixes, in particular: - Series expansion now handle poles of Gamma. - Fixed derivatives of meijerG. |
