* add overloads of lazyAssign to detect common aliasing issue withGravatar Gael Guennebaud2009-08-15
| | | | transpose and adjoint
* As proposed on the list:Gravatar Gael Guennebaud2009-08-15
| | | | | | | | | - rename EvalBeforeAssignBit to MayAliasBit - make .lazy() remove the MayAliasBit only, and mark it as deprecated - add a NoAlias pseudo expression, and MatrixBase::noalias() function Todo: - we have to decide whether += and -= assume no aliasing by default ? - once we agree on the API: update the Sparse module and the unit tests respectively.

* let the user disable alignment altogether by #defining EIGEN_DONT_ALIGN.Gravatar Benoit Jacob2009-05-03
| | | | | | | Until now, the user had to edit the source code to do that. Internally, add EIGEN_ALIGN that takes into account both EIGEN_DONT_ALIGN.and EIGEN_ARCH_WANTS_ALIGNMENT. From now on, only EIGEN_ALIGN should be used to test whether we want to align.

* add SSE2 versions of sin, cos, log, exp using code from JulienGravatar Gael Guennebaud2009-03-25
| | | | | | | | Pommier. They are for float only, and they return exactly the same result as the standard versions in about 90% of the cases. Otherwise the max error is below 1e-7. However, for very large values (>1e3) the accuracy of sin and cos slighlty decrease. They are about 3 or 4 times faster than 4 calls to their respective standard versions. So, is it ok to enable them by default in their respective functors ?
