* CXX11/TensorSymmetry: add symmetry support for Tensor classGravatar Christian Seiler2013-11-14
| | | | | | | | | | | | | | | | | | | | | | | | | Add a symCoeff() method to the Tensor class template that allows the user of the class to set multiple elements of a tensor at once if they are connected by a symmetry operation with respect to the tensor's indices (symmetry/antisymmetry/hermiticity/antihermiticity under echange of two indices and combination thereof for different pairs of indices). A compile-time resolution of the required symmetry groups via meta templates is also implemented. For small enough groups this is used to unroll the loop that goes through all the elements of the Tensor that are connected by this group. For larger groups or groups where the symmetries are defined at run time, a standard run-time implementation of the same algorithm is provided. For example, the following code completely initializes all elements of the totally antisymmetric tensor in three dimensions ('epsilon tensor'): SGroup<3, AntiSymmetry<0,1>, AntiSymmetry<1,2>> sym; Eigen::Tensor<double, 3> epsilon(3,3,3); epsilon.setZero(); epsilon.symCoeff(sym, 0, 1, 2) = 1;
* CXX11/Tensor: add simple initial tensor implementationGravatar Christian Seiler2013-11-14
| | | | | | | This commit adds an initial implementation of a class template Tensor that allows for the storage of objects with more than two indices. Currently, only storing data and setting the object to zero for POD data types are implemented.
* C++11: add template metaprogramming helpersGravatar Christian Seiler2013-11-14
| | | | | | | | Create a new directory CXX11 under unsupported/Eigen that contains code that requires C++11. In that directory, add a few generic templates useful for any module relying on C++11. These templates may be included with #include <[unsupported/]Eigen/CXX11/Core>. At the moment, this will only provide templates in the Eigen::internal namespace.

* Fix compilation.Gravatar Hauke Heibel2013-08-02
| | | | | | The Matrix is required to be mutable but it also needs to be a reference and temporaries do not bind to non-const references - thus we need a hack and cast away the constness.
