Changes in the kernel/build system:
- integrated xalloc into omalloc: (
./configure --disable-omalloc
) - improved heuristic for
det
( det) - improved reading of long polynomials
- improved groebner bases over Z coefficients
- code for free algebras (letterplace rings) rewritten (using now the standrad
+,-,*,^,std
,...) ( LETTERPLACE) - new commands
rightstd
( rightstd (letterplace)) - extended
twostd
to LETTERPLACE ( twostd (letterplace), twostd (plural)) - pseudo type
polyBucket
- new type
smatrix
: sparse matrix (experimental) ( smatrix). - extended
coef
to ideals ( coef). - error and signal handling in
libSingular
( libSingular). - updated gfanlib to version 0.6.2
- port to NTL 11 (needs C++11: gcc6 or -std=c++11), which does not conflict with polymake (needs C++14)
