Mike Bosse 80187362b8 attemping to expose ChartValue for expressions with non DefaultCharts, but needs testing 2014-10-28 11:20:02 +01:00
Mike Bosse bc094951ed all values in Values container are now a ChartValue<ValueType, Chart=DefaultChart<ValueType> >
ChartValues are GenericValues and a Chart, which defaults to DefaultChart
had to make charts functional (ie no storage of the chart origin) so that they could be zero sized base class
otherwise there would have been a double of the memory for values (ones for the value, and once for the chart origin, which default to the same)

most tests work, execept for serialization based stuff, and const filtering of values.

dellaert 625b939b66 Another very significant speed-up of reverseAD pipeline, by template specialization of the leaf case for fixed matrices. Unfortunately, while this sped up reverse AD for our SFM kernel by 300%, reverseAD was only 6%, and is now 2% of total time. So, time to look elsewhere.
Oh, and, it is clear that the Identity matrix for Leaf only expressions is completely known at compile time: Eigen::Matrix<double, T::dimension, T::dimension>::Identity(). That should nicely speed up many a PriorFactor (replacement).
