Member Function Documentation

bool compute_plif_matrix ( SGNDArray< float64_t > penalties_array )

parse an 3D array of plif ids and compute the corresponding 2D plif matrix by subsuming the third dim into one PlifArray; Note: the class PlifArray is derived from PlifBase. It computes all individual plifs and sums them up.

penalties_array 3D array of plif ids (nofstates x nofstates x nof(features for each transition))

Returns: success

Definition at line 182 of file PlifMatrix.cpp.

bool compute_signal_plifs ( SGMatrix< int32_t > state_signals )

Parameters

state_signals mapping of features to states

Returns: success

Definition at line 245 of file PlifMatrix.cpp.
