* add VectorwiseOp's +, -, +=, -= operators
|
| |
|
|
|

|

* add Homogeneous expression for vector and set of vectors (aka matrix)
=> the next step will be to overload operator*
* add homogeneous normalization (again for vector and set of vectors)
* add a Replicate expression (with uni-directional replication
facilities)
=> for all of them I'll add examples once we agree on the API
* fix gcc-4.4 warnings
* rename reverse.cpp array_reverse.cpp

* install QtAlignedMalloc
* finish the renaming Regression->LeastSquares
* install LeastSquares directory (!!!)
* misc dox fixes

* computation
* Array: add a count() method and rename AllAndAny.h file to
BooleanRedux.h

operator.
Example:
mat = (mat.cwise().abs().cwise() < Ones()).select(0,mat);
replaces all small values by 0. (the scalar version is "s = abs(s)<1 ? 0 : s")

Documentation:
* add an overview for each module.
* add an example for .all() and Cwise::operator<

- matrix-scalar addition/subtraction operators, e.g.:
m.array() += 0.5;
- matrix/matrix comparison operators, e.g.:
if (m1.array() < m2.array()) {}
* fix compilation issues with Transform and gcc < 4.1

* use ProductReturnType<>::Type to get the correct Product xpr type
* Product is no longer instanciated for xpr types which are evaluated
* vectorization of "a.transpose() * b" for the normal product (small and fixed-size matrix)
* some cleanning
* removed ArrayBase

This include:
- cwise Pow,Sin,Cos,Exp...
- cwise Greater and other comparison operators
- .any(), .all() and partial reduction
- random
