7031a851d4 Generalize matrix ctor and compute() method of dense decomposition to 1) limit temporaries, 2) forward expressions to nested decompositions, 3) fix ambiguous ctor instanciation for square decomposition 2015-09-07 10:42:04 +02:00

37a93c4263 New scoring functor to select the pivot. 
This is can be useful for non-floating point scalars, where choosing the biggest element is generally not the best choice.

98604576d1 Merged in chtz/eigen-indexconversion (pull request PR-92) 
bug #877, bug #572: Get rid of Index conversion warnings, summary of changes:

- Introduce a global typedef Eigen::Index making Eigen::DenseIndex and AnyExpr<>::Index deprecated (default is std::ptrdiff_t).

 - Eigen::Index is used throughout the API to represent indices, offsets, and sizes.

 - Classes storing an array of indices uses the type StorageIndex to store them. This is a template parameter of the class. Default is int.

 - Methods that *explicitly* set or return an element of such an array take or return a StorageIndex type. In all other cases, the Index type is used.

f8407742c1 Fix some implicit int64 to int conversion warnings. However, the real issue 
is that PermutationMatrix mixes the type of the stored indices and the "Index"
type used for the sizes, coeff indices, etc., which should be DenseIndex.
