jrc3_cuda_delta.cu

CUDA code to compute the distance separation Delta used for DPCLUS

Syntax

• jrc3_cuda_delta(float * vrDelta1, unsigned int * viNneigh1, const float * mrFet12, const int * viiSpk12_ord, const int * viiRho12_ord, const int * vnConst, const float dc2)

Input

• mrFet12: feature matrix (nC x n12: single)
• viiSpk12_ord: Temporal order of spikes (n12 x 1: int32)
• viiRho12_ord: Rho sort order (ascending order)
• vnConst: [n1, n12, nC, dn_max, fDc_spk]
  • n1: number of spikes to compute rho
  • n12: total number of spikes
  • nC: number of features
  • dn_max: max. time index difference
  • fDc_spk: Flag to compute dc on fly. Set to 0 if you supplied dc2.
• dc2: Distance cut-off squared (single)

Output

• vrDelta1: distance separation (n1 x 1: single)
• viNneigh1: Nearest neighbor index
