Eigen 3.2.9
Released on July 18, 2016
Changes since 3.2.8:
* Main fixes and improvements:
+ Improve numerical robustness of JacobiSVD (backported from 3.3)
+ Bug 1017: prevents underflows in makeHouseholder
+ Fix numerical accuracy issue in the extraction of complex
eigenvalue pairs in real generalized eigenvalue problems.
+ Fix support for vector.homogeneous().asDiagonal()
+ Bug 1238: fix SparseMatrix::sum() overload for un-compressed mode
+ Bug 1213: workaround gcc linking issue with anonymous enums.
+ Bug 1236: fix possible integer overflow in sparse-sparse product
+ Improve detection of identical matrices when applying a
permutation (e.g., mat = perm * mat)
+ Fix usage of nesting type in blas_traits. In practice, this
fixes compilation of expressions such as A*(A*A)^T
+ CMake: fixes support of Ninja generator
+ Add a StorageIndex typedef to sparse matrices and expressions
to ease porting code to 3.3 (see
http://eigen.tuxfamily.org/index.php?title=3.3#Index_typedef)
+ Bug 1200: make aligned_allocator c++11 compatible (backported from 3.3)
+ Bug 1182: improve generality of abs2 (backported from 3.3)
+ Bug 537: fix compilation of Quaternion with Apples's compiler
+ Bug 1176: allow products between compatible scalar types
+ Bug 1172: make valuePtr and innerIndexPtr properly return null
for empty sparse matrices.
+ Bug 1170: skip calls to memcpy/memmove for empty inputs.
* Others:
+ Bug 1242: fix comma initializer with empty matrices.
+ Improves support for MKL's PARDISO solver.
+ Fix a compilation issue with Pastix solver.
+ Add some missing explicit scalar conversions
+ Fix a compilation issue with matrix exponential (unsupported
MatrixFunctions module).
+ Bug 734: fix a storage order issue in unsupported Spline module
+ Bug 1222: fix a compilation issue in AutoDiffScalar
+ Bug 1221: shutdown some GCC6's warnings.
+ Bug 1175: fix index type conversion warnings in sparse to
dense conversion.
Eigen 3.2.8
Released on February 16, 2016
Changes since 3.2.7:
* Main fixes and improvements:
+ Make FullPivLU::solve use rank() instead of nonzeroPivots().
+ Add EIGEN_MAPBASE_PLUGIN
+ Bug 1166: fix issue in matrix-vector products when the
destination is not a vector at compile-time.
+ Bug 1100: Improve cmake/pkg-config support.
+ Bug 1113: fix name conflict with C99's "I".
+ Add missing delete operator overloads in
EIGEN_MAKE_ALIGNED_OPERATOR_NEW
+ Fix (A*B).maxCoeff(i) and similar.
+ Workaround an ICE with VC2015 Update1 x64.
+ Bug 1156: fix several function declarations whose arguments
were passed by value instead of being passed by reference
+ Bug 1164: fix std::list and std::deque specializations such
that our aligned allocator is automatically activatived only
when the user did not specified an allocator (or specified the
default std::allocator).
* Others:
+ Fix BLAS backend (aka MKL) for empty matrix products.
+ Bug 1134: fix JacobiSVD pre-allocation.
+ Bug 1111: fix infinite recursion in
sparse-column-major.row(i).nonZeros() (it now produces a
compilation error)
+ Bug 1106: workaround a compilation issue in Sparse module for
msvc-icc combo
+ Bug 1153: remove the usage of __GXX_EXPERIMENTAL_CXX0X__ to
detect C++11 support
+ Bug 1143: work-around gcc bug in COLAMD
+ Improve support for matrix products with empty factors.
+ Fix and clarify documentation of Transform wrt
operator*(MatrixBase)
+ Add a matrix-free conjugate gradient example.
+ Fix cost computation in CwiseUnaryView (internal)
+ Remove custom unaligned loads for SSE.
+ Some warning fixes.
+ Several other documentation clarifications.
