Upgrade to release 1.8:
assumptions:
- Q.infinite now correctly evaluates to True for oo, -oo, and zoo
- Assumption predicates now correctly evaluates to None for S.NaN
- Relational objects do not need to be wrapped by Q.is_true to be
asked or refined anymore
- Q.is_true wrapping over AppliedPredicate now just return the
argument
- refine arg(x) when x is real and nonzero
- assumptions/relation module is introduced. This module
implements binary relation as predicate
- AskHandler(), register_handler() and remove_handler() are
deprecated. Handler now must be multipledispatch instance
- Predicate now uses a single handler which is multipledispatch
instance
- Predicate can now take multiple arguments
- Predicate("...") now returns UndefinedPredicate instance. To
define a predicate, you must make a subclass of Predicate
calculus:
- Using maximum with a piecewise expression over a domain no
longer fails due to a bug fix in Piecewise.as_expr_set_pairs
codegen:
- allowing for multi-dimensional arrays as arguments/locals in c
code generation
- create_expand_pow_optimization is now customizable with respect
to requirement on base
- Support flattening of elementwise additions of array expressions
- Fixes to array-expressions in order to properly work with
ZeroArray and ZeroMatrix
- Fixing matrix expression recognition from array-expressions
- Minor fixes to the way the AST of array expressions is built
- Add normalization of CodegenArrayDiagonal when it's nested with
CodegenArrayPermuteDims and CodegenArrayContraction
- Increased support for the normalization of array expressions and
permutations of indices
- parse_matrix_expression( ) is now able to parse traces of
matrices
combinatorics:
- Added a section to the permutation docs about containment in
permutation groups
geometry:
- Fix AssertError for vertical tangent
- Geometric entities with symbolic coordinates will not be printed
in SVG
simplify:
- Fix simplify calls sympify without rational parameter
- TRmorrie now takes powers of cos terms into account
tensor:
- Introduced objects ArraySymbol and ArrayElement for array
expressions equivalent to MatrixSymbol and MatrixElement in the
matrix expression module
- Add class ZeroArray for array expressions of zero-valued
elements
- Make Array differentiation(derive_by_array) work with non sympy
expressions
- Added tensordiagonal( ) function to perform diagonalization of
array expressions
- Adding an array with any other type now consistently gives
NotImplemented
utilities:
- Added official support for using CuPy to GPU accelerate lambdify
functions
- Added Replacer class to simplify the creation of replacement
expressions with MatchPy
- Added tests for optional parameter in MatchPy patterns
- Added string printers for MatchPy-compatible wildcards in
sympy.utilities.matchpy_connector
- minlex no longer accepts is_set or small arguments
- minlex and least_rotation now accept key= arguments similar to
sorted
vector:
- Fixed a bug with integral over ImplicitRegion objects
other:
- Expanding documentation to include all class members with
docstrings
