Adolfo Rodriguez Tsouroukdissian	5a36f4a8d1	Propagate all five matrix template parameters to members and temporaries of decomposition classes. One particular advantage of this is that decomposing matrices with max sizes known at compile time will not allocate. ... NOTE: The ComplexEigenSolver class currently _does_ allocate (line 135 of Eigenvalues/ComplexEigenSolver.h), but the reason appears to be in the implementation of matrix-matrix products, and not in the decomposition itself. The nomalloc unit test has been extended to verify that decompositions do not allocate when max sizes are specified. There are currently two workarounds to prevent the test from failing (see comments in test/nomalloc.cpp), both of which are related to matrix products that allocate on the stack.	2010-03-08 19:31:27 +01:00
Gael Guennebaud	c5d7c9f0de	remove the Triangular suffix to Upper, Lower, UnitLower, etc, ... and remove the respective bit flags	2010-01-07 21:15:32 +01:00
Benoit Jacob	39ac57fa6d	Big renaming: ... start ---> head end ---> tail Much frustration with sed syntax. Need to learn perl some day.	2010-01-04 21:24:43 -05:00
