compute_L_matrix_cpp: Compute L matrix for V update (C++ version)
In NetworkChange: Bayesian Package for Network Changepoint Analysis
compute_L_matrix_cpp R Documentation
Compute L matrix for V update (C++ version)
Description
Computes L(t, r) = sum over i less than j of Z(i,j,t) * U(i,r) * U(j,r)
This is a key bottleneck in updateV.
Usage
compute_L_matrix_cpp(Z, U, T_dim, R)
Arguments
Z
3D array (N x N x T), already zeroed below diagonal
U
Factor matrix (N x R)
T_dim
Number of time points
R
Number of latent dimensions
Value
T_dim x R matrix L
