* mainly enhance MatrixLogarithm's performance for RealScalar != doubleGravatar Chen-Pang He2011-09-17
|
* Define log2() on FreeBSD (fixes bug #343).Gravatar Jitse Niesen2011-09-06
|
* Add defensive assert to MatrixExponential,Gravatar Jitse Niesen2011-09-03
|
* enhance efficacy via avoiding exception handlingGravatar Chen-Pang He2011-09-02
|
* Leverage triangular square root in matrix log.Gravatar Jitse Niesen2011-08-25
|
* Split code for (quasi)triangular matrices from MatrixSquareRoot.Gravatar Jitse Niesen2011-08-25
| | | | This way, (quasi)triangular matrices can avoid the costly Schur decomposition.
* fix: <ctime> is necessary for srand(time(NULL))Gravatar Chen-Pang He2011-08-24
|
* add compatibility with long doubleGravatar Chen-Pang He2011-08-20

* the min/max macros to detect unprotected min/max were undefined by some std ↵Gravatar Gael Guennebaud2011-08-19
| | | | | | header, so let's declare them after and do the respective fixes ;)
* Remove unnecessary template keywords (breaks compilation under MSVC).Gravatar Jitse Niesen2011-07-28
| | | | Thanks to Hauke for finding this.
* protect calls to min and max with parentheses to make Eigen compatible with ↵Gravatar Gael Guennebaud2011-07-21
| | | | | | | default windows.h (transplanted from 49b6e9143e1d74441924c0c313536e263e12a55c )
* Implement matrix logarithm + test + docs.Gravatar Jitse Niesen2011-06-07
| | | | Currently, test matrix_function_1 fails due to bug #288.
* Decouple MatrixFunction and MatrixFunctionAtomicGravatar Jitse Niesen2011-06-07
| | | | in preparation for implementation of matrix log.
* Fix and test MatrixSquareRoot for 1-by-1 matrices.Gravatar Jitse Niesen2011-06-07
|
* Fix typo ('using namespace' instead of 'using').Gravatar Jitse Niesen2011-05-26
|
* Simplify the use of custom scalar types, the rule is to never directly call ↵Gravatar Gael Guennebaud2011-05-25
| | | | | | | a standard math function using std:: but rather put a using std::foo before and simply call foo: using std::max; max(a,b);
* Implement and document MatrixBase::sqrt().Gravatar Jitse Niesen2011-05-09
|
* Fix compilation error under GCC 4.5.Gravatar Jitse Niesen2011-05-09
| | | | | That version is stricter in forcing function prototype and definition to match.
* Implement square root for real matrices via Schur.Gravatar Jitse Niesen2011-05-08
|
* Implement matrix square root for complex matrices.Gravatar Jitse Niesen2011-05-07
| | | | | I hope to implement the real case soon, but it's a bit more complicated due to the 2-by-2 blocks in the real Schur decomposition.
* bug #54 - really fix const correctness except in SparseGravatar Benoit Jacob2010-12-22
|
* bug #86 : use internal:: namespace instead of ei_ prefixGravatar Benoit Jacob2010-10-25
|
* rename PlanarRotation -> JacobiRotationGravatar Benoit Jacob2010-10-19
|
* Finally fixed the matrix function/exponential warning.Gravatar Hauke Heibel2010-06-20
| | | | Index fixes.
* Attempt to fix MatrixExponential/Function related warnings.Gravatar Hauke Heibel2010-06-20
|
* Ups, fixed a little ugly bug.Gravatar Hauke Heibel2010-06-15
|
* Fixed 64bit/Index related warnings in the matrix functions module.Gravatar Hauke Heibel2010-06-15
|
* Fixed warnings regarding missing assignment operator.Gravatar Hauke Heibel2010-06-11
|
* the Index types change.Gravatar Benoit Jacob2010-05-30
| | | | As discussed on the list (too long to explain here).
* * implement the corner() API change: new methods topLeftCorner() etcGravatar Benoit Jacob2010-04-22
| | | | | | | | * get rid of BlockReturnType: it was not needed, and code was not always using it consistently anyway * add topRows(), leftCols(), bottomRows(), rightCols() * add corners unit-test covering all of that * adapt docs, expand "porting from eigen 2 to 3" * adapt Eigen2Support
* Move documentation of MatrixBase methods in MatrixFunctions to module page.Gravatar Jitse Niesen2010-03-22
| | | | | | | I think that because MatrixFunctions is in unsupported/ and MatrixBase is not, doxygen does not include the MatrixBase methods defined and documented in the MatrixFunctions module with the other MatrixBase methods. This is a kludge, but at least the documentation is not lost.
* API change: ei_matrix_exponential(A) --> A.exp(), etcGravatar Jitse Niesen2010-03-16
| | | | | As discussed on mailing list; see http://listengine.tuxfamily.org/lists.tuxfamily.org/eigen/2010/02/msg00190.html

| * Change MatrixFunction::separation() parameter from 0.01 to 0.1 .Gravatar Jitse Niesen2010-02-20
| | | | | | | | The latter is actually the value used in the literature.
* | Renamed PlainMatrixType to PlainObject (Array != Matrix).Gravatar Hauke Heibel2010-02-20
| | | | | | | | Renamed ReturnByValue::ReturnMatrixType ReturnByValue::ReturnType (again, Array != Matrix).
| * matrix_function test: replace expm(A).inverse() by expm(-A)Gravatar Jitse Niesen2010-02-20
|/ | | | | | The latter is more stable. This fixes one of the issues with the test. Also, make typedef's in MatrixFunctionReturnValue public; this is necessary to get the test to compile.

* Use ReturnByValue to return result of ei_matrix_exponential() .Gravatar Jitse Niesen2010-02-15

* fix compilation (cwise and epsilon)Gravatar Gael Guennebaud2010-02-11

* triangularView<UpperTriangular> --> triangularView<Upper>Gravatar Jitse Niesen2010-01-08
| | | | | Necessary after c5d7c9f0def693e77797e6e43cb1fd2e7f8ae2fd (big delete of "triangular").
