use new-style print methods
subs() and normal() use maps instead of lists, resulting in a huge performance boost for subs()
merging 1.2 branch into main trunk
synced to 1.1
implemented relational::subs()
- removed copy(), destroy(), copy constructors, destructors and assignment operators from all classes except basic, because the defaults work just fine (and this also speeds up things a little) - clarified the behavior of basic copy constructor vs. basic assignment op
func(void) -> func() (this is C++, dammit :)
return type and parameter type of nops() and op()/let_op() (respectively) is now a size_t
- added non-const operator[] - removed let_op() for power and relational - removed redundant matrix::op()
*** empty log message ***
- prepared for 1.0.13 release - synced to 1.1
- synced to 1.0 (gammaL/R) - removed dirac_gamma6/7() - renamed simplify_ncmul() to eval_ncmul(), as it should have been called from the beginning
implemented relational::subs()
* Apply safe-bool patch.
* Sync 1.1 branch to 1.0 mainline.
* Finilize version 1.0.4 (version numbers, copyrights and such rubbish).
* Added output-support for Python bindings and LaTeX printing for indexed objects (Pearu Peterson). * relational.*: Removed superfluous is_equal_same_type()... * inifcns_trans.cpp: ...added extern declaration as workaround for compiler-bug triggered by changes to relational.*, * input_parser.yy: added missing namespace specification.
* Add Pearu's patch canonicalizing class relational, augmented by missing logic in compare_same_type().
- Cleanups: My evil plot of making ex::bp private may finally be carried out, provided one changes all the is_of_type(obj,type) to is_a<type>(obj) which we don't do right now because it would degrade performance on gcc-2.95.x. Also, ex_to_type(obj) has gone for good now, we have been having ex_to<type>(obj) long enough. ex_to_nonconst_type(obj) have gone as well, since they are almost never used and one can always cast aways the constness explicitly if need should arise.
- replaced the Derivative() function by a more resonable fderivative class; to see it in action, try "series(abs(x),x==0,3)" and "series(abs(x),x==y,3)" in ginsh with previous GiNaC releases and with this one - add::eval() throws an exception when the first term is non-commutative and the overall_coeff is non-zero - small fixes to print_tree output of indexed objects - ncmul::expand() now actually does expand something like "(dirac_gamma(mu)+1) *dirac_gamma(nu)" correctly (but the change to add::eval() should make this a "can't happen" case) - moved ToString() to tostring.h (fewer header dependencies) - ALL YOUR "BASES CLASSES" ARE BELONG TO US
- added find() (like has(), but returns list of all occurrences)
- added lst::sort() and lst::unique()
- status_flags::expanded is only taken into account when no expand options
are specified. This makes it possible to re-expand with other options.
- added expand_options::expand_function_args
- collect(foo, {}) doesn't crash any more
- introduced match_same_type() method which is slightly similar to
is_equal_same_type() but doesn't check subexpressions. Fixed a number of
match() bugs with this (e.g. a==b matched a!=b, and matrices with different
dimensions but the same number of elements could match). Only container
classes with additional member variables that have to be equal for a match
need to implement match_same_type().
- The default implementations of evalf(), diff(), normal() and expand() use map() where useful. This has the nice effect of having a more reasonable default behaviour for container functions (most of the evalfchildren() etc. stuff is gone). - diff() works with non-commutative products (product rule) and no longer bails on indexed objects. - added decomp_rational() - added sqrfree_parfrac() which doesn't yet work in the general case and is unsupported
* Supplement some (now deprecated) macros by inlined template functions: - ex_to_foobar(baz) -> ex_to<foobar>(baz).
* Supplement some (now deprecated) macros by inlined template functions: - is_of_type(foo, type) -> is_a<type>(foo) - is_ex_of_type(foo, type) -> is_a<type>(foo) - is_exaclty_of_type(foo, type) -> is_exaclty_a<type>(foo) - is_ex_exaclty_of_type(foo, type) -> is_exaclty_a<type>(foo)
- Instead of just totally symmetric or antisymmetric, complex symmetries can now be defined for indexed objects. Symmetries are described by a tree of "symmetry" objects that is constructed with the sy_none(), sy_symm(), sy_anti() and sy_cycl() functions. The symmetry of a function with respect to its arguments can also be defined (this is currently only used for the Beta function). - color_trace() and dirac_trace() can be applied to a more general class of expressions, e.g. using it on a relation will take the trace on both sides etc. - Generalized map() to take a function object instead of a function pointer. This allows passing an arbitrary number of additional state to the function being called. - The unarchiving functinos find_bool(), find_unsigned() and find_string() can take an additional "index" argument.
- in the output, list delimiters are now { } and matrix delimiters are [ ]
- added evalm() method for evaluating sums and products of matrices
- added map() method for applying a function to subexpressions
- power(noncommut, posint) automatically expands the product, removed ncpow()
replaced "precedence" static member variable by virtual precedence() function
- replaced the various print*() member functions by a single print() that takes a print_context object that determines the output formatting; this should make it easier to add more output types - print_tree output of indexed objects looks better
* ginac/registrar.h: dtor is inlined now. * ginac/basic.h, ginac/ex.h: removed INLINE_FOO_CONSTRUCTORS and hand-inlined stuff instead, since the macros turned out to get in the way while fine-tuning the inlining. * ginac/utils.h: if 'long long' works, use that one for computing the hash value instead of floating point tricks. 2 Reasons: on Intel the assembler is terrible and slow otherwise, 'long long' will appear in C++ anyways when they adapt to the C99 standard. * Several other small performance tweaks. * ginac/constant.cpp: (constant::calchash()) implement, caring for serial. * ginac/function.pl (function::calchash()): implement, caring for serial. * ginac/expairseq.cpp: honor coeff's hash value. * ginac/pseries.cpp: (pseries::power_const()) fix problems with zero pseries. * Added several pounds of in-source documentation in doxygen style.
GINAC_DECLARE_REGISTERED_CLASS declares duplicate() and compare_same_type(), GINAC_IMPLEMENT_REGISTERED_CLASS implements duplicate()
the destructor, copy constructor, and assignment operator (which were the same for all subclasses of basic, with very few exceptions) are now included in the GINAC_IMPLEMENT_REGISTERED_CLASS macro; the GINAC_DECLARE_REGISTERED_CLASS macro also defines these (and other common) member functions
removed the "some_*" and "typeid_*" definitions since we are using our own RTTI for quite some time now
- See if __GNUC__ < 2.97 before using std::vector<..,malloc_alloc>. Sorry, there is no way having this depend on whether we are setting up Cint or not because the malloc_alloc goes into the mangled signature and the result won't link if one tries to be more clever. It really sucks. Let's all just pray Masaharu throws away that old STL implementation really soon now. (Jeez, he still calls this old junk 'reference'!) - Bumped up a few dates. :-)
- Inserted some more std:: to make it compile under GCC2.96.
- fixes to the indentation
- indentation is now done with tabs - printtree() prints the class names as known to the registrar, not the (mangled) class names from typeid().name()
- Derivatives are now assembled in a slightly different manner (i.e. they 'look' different on first sight). Under certain circumstances this can result in a dramatic speedup because it gives hashing a better chance, especially when computing higher derivatives. - Series expansion accepts an additional bool argument now, telling it whether branch cuts are to be honored (as Maple does it) or not (as Mathematica does it). It defaults to true (i.e. the Maple way). - Many series expansions of built-in functions have been reengineered. - The Dilogarithm (Li2) now has floating point evaluation, derivative and a proper series expansion. - Namespace 'std' cleanly disentangled, as demanded by ISO/EIC 14882-1998(E). - Some helpers updated from upstream.
- normal() works for relationals: it normalizes both sides
- */Makefile.in: changes triggered by newer automake. - added relational::rhs() and relational::lhs() also available from ex. - added two new checks in check/linear_solve.cpp (formerly check/lsolve_onedim.cpp) shamelessly ripped from the Maple online-help. - added keyword warranty to ginsh as dictated by the bible (emacs).
- Renamed flag NO_GINAC_NAMESPACE to NO_NAMESPACE_GINAC because of m4. - Made configure check for cint and makecint and call makecint to dump out cint/Makefile.cint, which will later be called by cint/Makefile. See configure option --with-cint. - Added some documentation about GiNaC-cint (e.g. a manpage). - All dummies in subdir cint/ are created by cint/dummies.pl now, removed older stuff.
- building GiNaC in a separate directory now works
- changed all instances of "foo const &/*" to "const foo &/*" - changed function arguments like "int const" to a simple "int"
- implemented global class registry (for class basic and derived classes) - implemented archiving of expressions (except for class idx, and all classes derived from idx and indexed) - added series() wrapper function - class series renamed to pseries to avoid name clashes with global series() wrapper function, ex::series(), and basic::series() - corrected the series expansion of single symbols with respect to the order term - calling subs() on a series didn't work
- made nops() return unsigned instead of int - changed dates in copyright notices
- introduced info_flags::cinteger, info_flags::crational, info_flags::cinteger_polynomial, info_flags::crational_polynomial with intuitive behaviour. - extended documentation - made things like evlaf(zeta(3)) work - killed several bugs
#ifndef around namespace GiNaC { }
- put everything in "GiNaC" namespace - converted some macros into inline functions - split debugmsg.h into assertion.h (public) and debugmsg.h (private)
- modified the comment blocks so the copyright message no longer appears in the reference manual (made by Doxygen)
- modified GiNaC headers to Alexander's liking
- enforced GiNaC coding standards :-)
- switched to automake build environment
