Detailed Description

template<typename DeviceType, typename SHEQuantityT>
class viennashe::she::df_wrapper< DeviceType, SHEQuantityT >

A convenience wrapper for evaluating the full distribution function. Note: Evaluations are quite costly. If you wish to evaluate integrals over the distribution function, you should definitely consider the use of SHE expansion coefficients as well as the orthogonality relations for spherical harmonics.

Template Parameters

DeviceType	The device type on which to evaluate the distribution function
VectorType	Vector type used for the SHE result vector.

Returns the energy distribution function for electrons in one valley on a vertex:

Parameters

cell	The cell from which the SHE coefficient should be returned
kinetic_energy	Kinetic energy
theta	Polar angle
phi	Azimuthal angle
index_H_guess	The total energy index for starting the search for the best total energy index available. Allows to speed-up evaluation considerably.
