Eigen 3.0-beta1
Not yet released
See the announcement.
Eigen 2.0.14
Released June 22, 2010
Changes since 2.0.13:
- Fix #141: crash in SSE (alignment problem) when using dynamic-size matrices with a max-size fixed at compile time that is not a multiple of 16 bytes. For example, Matrix<double,Dynamic,Dynamic,AutoAlign,5,5>.
- Fix #142: LU of fixed-size matrices was causing dynamic memory allocation (patch by Stuart Glaser).
- Fix #127: remove useless static keywords (also fixes warnings with clang++).
Eigen 2.0.13
Released June 10, 2010
Changes since 2.0.12:
- Fix #132: crash in certain matrix-vector products. Unit test added.
- Fix #125: colwise norm() and squaredNorm() on complex types do not return real types
- Fully support the QCC/QNX compiler (thanks to Piotr Trojanek). The support in 2.0.12 was incomplete. The whole test suite is now successful.
- As part of the QCC support work, a lot of standards compliance work: put std:: in front of a lot of things such as size_t, check whether the math library needs to be linked to explicitly...
- Fix precision issues in LDLT. The isPositiveDefinite() method is now always returning true, but it was conceptually broken anyway, since a non-pivoting LDLT decomposition can't know that.
- Compilation fix in ldlt() on expressions.
- Actually install the Eigen/Eigen and Eigen/Dense public headers!
- Fix readcost for complex types.
- Fix compilation of the BTL benchmarks.
- Some dox updates.
Eigen 2.0.12
Released February 12, 2010
Changes since 2.0.11:
- EIGEN_DEFAULT_TO_ROW_MAJOR is fully supported and tested.
- Several important fixes for row-major matrices.
- Fix support of several algorithms for mixed fixed-dynamic size matrices where the fixed dimension is greater than the dynamic dimension. For example: Matrix<float,3,Dynamic>(3,2)
- fix EIGEN_DONT_ALIGN: now it _really_ disables vectorization (was giving a #error unless you also used EIGEN_DONT_VECTORIZE).
- Fix #92: Support QNX's QCC compiler (patch by Piotr Trojanek)
- Fix #90, missing type cast in LU, allow to use LU with MPFR (patch by 'Wolf').
- Fix ICC compiler support: work around a bug present at least in ICC 11.1.
- Compilation fixes for computeInverse() on expressions.
- Fix a gap in a unit-test (thanks to Jitse Niesen)
- Backport improvements to benchmarking code.
- Documentation fixes
Eigen 2.0.11
Released January 10, 2010
Changes since 2.0.10:
- Complete rewrite of the 4x4 matrix inversion: we now use the usual cofactors approach, so no numerical stability problems anymore (bug #70)
- Still 4x4 matrix inverse: SSE path for the float case, borrowing code by Intel, giving very high performance.
- Fix crash happening on 32-bit x86 Linux with SSE, when double's were created at non-8-byte-aligned locations (bug #79).
- Fix bug in Part making it crash in certain products (bug #80).
- Precision improvements in Quaternion SLERP (bug #71).
- Fix sparse triangular solver for lower/row-major matrices (bug #74).
- Fix MSVC 2010 compatibility.
- Some documentation improvements.
Eigen 2.0.10
Released November 25, 2009
Changes since 2.0.9:
- Rewrite 4x4 matrix inverse to improve precision, and add a new unit test to guarantee that precision. It's less fast, but it's still faster than the cofactors method.
- Fix bug #62: crash in SSE code with MSVC 2008 (Thanks to Hauke Heibel).
- Fix bug #65: MatrixBase::nonZeros() was recursing infinitely
- Fix PowerPC platform detection on Mac OSX.
- Prevent the construction of bogus MatrixBase objects and generate good compilation errors for that. Done by making the default constructor protected, and adding some private constructors.
- Add option to initialize all matrices by zero: just #define EIGEN_INITIALIZE_MATRICES_BY_ZERO
- Improve Map documentation
- Install the pkg-config file to share/pkgconfig, instead of lib/pkgconfig (thanks to Thomas Capricelli)
- fix warnings
- fix compilation with MSVC 2010
- adjust to repository name change
Eigen 2.0.9
Released October 24, 2009
Changes since 2.0.8:
- Really fix installation and the pkg-config file.
- Install the NewStdVector header that was introduced in 2.0.6.
Eigen 2.0.8
Released October 23, 2009
Changes since 2.0.7:
- fix installation error introduced in 2.0.7: it was choking on the pkg-config file eigen2.pc not being found. The fix had been proposed long ago by Ingmar Vanhassel for the development branch, and when recently the pkg-config support was back-ported to the 2.0 branch, nobody thought of backporting this fix too, and apparently nobody tested "make install" !
- SVD: add default constructor. Users were relying on the compiler to generate one, and apparenty 2.0.7 triggered a little MSVC 2008 subtlety in this respect. Also added an assert.
Eigen 2.0.7
Released October 22, 2009
Changes since 2.0.6:
- fix bug #61: crash when using Qt QVector on Windows 32-bit. By Hauke Heibel.
- fix bug #10: the reallocateSparse function was half coded
- fix bug in SparseMatrix::resize() not correctly initializing by zero
- fix another bug in SparseMatrix::resize() when outerSize==0. By Hauke Heibel.
- fully support GCC 3.3. It was working in 2.0.2, there was a compilation error in 2.0.6, now for the first time in 2.0.7 it's 100% tested (the test suite passes without any errors, warnings, or failed tests).
- SVD: add missing assert (help catch mistakes)
- fixed warnings in unit-tests (Hauke Heibel)
- finish syncing Memory.h with the devel branch. This is cleaner and fixes a warning. The choice of system aligned malloc function may be affected by this change.
- add pkg-config support by Rhys Ulerich.
- documentation fix and doc-generation-script updates by Thomas Capricelli
Eigen 2.0.6
Released September 23, 2009
Changes since 2.0.5:
- fix bug: visitors didn't work on row-vectors.
- fix bug #50: compilation errors with swap().
- fix bug #42: Add Transform::Identity() as mentioned in the tutorial.
- allow to disable all alignment code by defining EIGEN_DONT_ALIGN (backport from devel branch).
- backport the devel branch's StdVector header as NewStdVector. You may also #define EIGEN_USE_NEW_STDVECTOR to make StdVector use it automatically. However, by default it isn't used by StdVector, to preserve compatibility.
- Vectorized quaternion product (for float) by Rohit Garg (backport from devel branch).
- allow to override EIGEN_RESTRICT and add EIGEN_DONT_USE_RESTRICT_KEYWORD
- fix a warning in ei_aligned_malloc; fixed by backporting the body from the devel branch; may result in a different choice of system aligned malloc function.
- update the documentation.
Eigen 2.0.5
Released August 22, 2009
Changes since 2.0.4:
- fix bug: in rare situations involving mixed storage orders, a matrix product could be evaluated as its own transpose
- fix bug: LU::solve() crashed when called on the LU decomposition of a zero matrix
- fix bug: EIGEN_STACK_ALLOCATION_LIMIT was too high, resulting in stack overflow for a user. Now it is set as in the devel branch.
- fix compilation bug: our StdVector header didn't work with GCC 4.1. (Bug #41)
- fix compilation bug: missing return statement in Rotation2D::operator*= (Bug #36)
- in StdVector, a more useful #error message about the #including order
- add EIGEN_TRANSFORM_PLUGIN allowing to customize the Transform class
- fix a warning with MSVC
- fix a bug in our cmake code when building unit-tests (thanks to Marcus Hanwell)
- work around a bug in cmake that made it fail to build unit-tests when fortran wasn't installed
- in our cmake code, remove the part about retrieving the mercurial info and appending it to the version number in the dox
- dox: remove the old example list
- fix the option to build a binary library, although it's not very useful and will be removed
- add basic .hgignore file and script to build the docs (thanks to Thomas Capricelli)
Eigen 2.0.4
Released August 1, 2009
Changes since 2.0.3:
- Several fixes in the overloaded new and delete operators. Thanks to Hauke Heibel.
- compilation fix: add the missing ei_atan2 function. Thanks to Manuel Yguel.
- Use ei_atan2 instead of using std::atan2 directly.
- several compilation fixes in the Qt interoperability code: methods toQTransform() and toQMatrix(). Thanks to Anthony Truchet.
- compilation fix and simplification in Matrix assignment
- compilation fixes in "a *= b" and "a=a*b" when a has to be resized.
- remove a "stupid" version of ei_pow. for integers for gcc >= 4.3
- bug fix in Quaternion::setFromTwoVectors()
- several ctest improvements: use our own dashboard, use a separate project for the 2.0 branch.
- documentation: improvement on the pages on unaligned arrays (the online copies have been updated immediately).
Eigen 2.0.3
Released June 21, 2009
Changes since 2.0.2:
- precision and reliability fixes in various algorithms, especially LLT, QR, Tridiagonalization, and also a precision improvement in LU.
- fix LLT and LDLT solve() on uninitialized result (was causing an assertion).
- add Eigen/Eigen and Eigen/Dense headers for convenience

- updates in the Sparse module (was needed to support KDE 4.3)
Eigen 2.0.2
Released May 22, 2009
Changes since 2.0.1:
- Fix linearRegression() compilation, actually it is reimplemented using the better fitHyperplane() which does total least-squares.
- Add missing setZero() etc... variants taking size parameters and resizing. These were mentioned in the tutorial but weren't implemented.
- Fix posix_memalign platform check. This fixes portability issues. Thanks to Ross Smith.
- Fix detection of SSE2 on the Windows 64-bit platform.
- Fix compatibility with the old GCC 3.3: it is now fully supported again.
- Fix warnings with recent GCC (4.4.0 and 4.3.3).
Eigen 2.0.1
Released April 14, 2009
Changes since 2.0.0:
- disable alignment altogether on exotic platforms on which we don't vectorize anyway. This allows e.g. to use Eigen on ARM platforms.
- new StdVector header with a new workaround for the problems with std::vector.
- workarounds for MSVC internal compiler errors
- MSVC 9 compilation fix (patch by Hauke Heibel)
- fixes for various bugs in Maps/Blocks that could give wrong results
