updateU: Update time-constant latent node positions

In NetworkChange: Bayesian Package for Network Changepoint Analysis

Update time-constant latent node positions

Description

Update time-constant latent node positions using optimized matrix operations. Pre-computes invariant quantities outside the node loop for better performance.

Usage

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

Arguments

K	The dimensionality of Z
U	The most recent draw of latent node positions
V	Layer-specific network generation rule
R	The dimensionality of latent space
Zb	Z - beta
s2	error variance
eU	The mean of U
iVU	The variance of U

Value

A matrix of time-constant latent node positions
