Benoit Jacob	aebecae510	* find the proper way of nesting the expression in Flagged: ... finally that's more subtle than just using ei_nested, because when flagging with NestByValueBit we want to store the expression by value already, regardless of whether it already had the NestByValueBit set. * rename temporary() ----> nestByValue() * move the old Product.h to disabled/, replace by what was ProductWIP.h * tweak -O and -g flags for tests and examples * reorder the tests -- basic things go first * simplifications, e.g. in many methoeds return derived() and count on implicit casting to the actual return type. * strip some not-really-useful stuff from the heaviest tests	2008-05-28 04:38:16 +00:00
Benoit Jacob	953efdbfe7	- introduce Part and Extract classes, splitting and extending the former ... Triangular class - full meta-unrolling in Part - move inverseProduct() to MatrixBase - compilation fix in ProductWIP: introduce a meta-selector to only do direct access on types that support it. - phase out the old Product, remove the WIP_DIRTY stuff. - misc renaming and fixes	2008-05-27 05:47:30 +00:00
Gael Guennebaud	94e1629a1b	* improved product performance: ... - fallback to normal product for small dynamic matrices - overloaded "c += (a * b).lazy()" to avoid the expensive and useless temporary and setZero() in such very common cases. * fix a couple of issues with the flags	2008-05-22 14:51:25 +00:00
Benoit Jacob	5da60897ab	Introduce generic Flagged xpr, remove already Lazy.h and Temporary.h ... Rename DefaultLostFlagMask --> HerediraryBits	2008-05-14 08:20:15 +00:00
