In NetworkChange: Bayesian Package for Network Changepoint Analysis

Update Time-constant Latent Node Positions (C++ version)

Description

Updates U using optimized matrix operations with pre-computed invariants.

Usage

updateU_cpp(K, U, V, R, Zb, s2, eU, iVU)

Arguments

K	Dimensions of Z (N, N, T)
U	Current latent node positions (N x R)
V	Layer-specific network generation rule (T x R)
R	Dimension of latent space
Zb	3D array (Z - beta)
s2	Error variance (scalar)
eU	Prior mean vector for U
iVU	Prior precision matrix for U

Value

Updated U matrix (N x R)
