convergence
Usage
vardi.algorithm(A, Y, lambda, tol = 0.001)
Arguments
A
routing matrix (m x k)
Y
matrix of link loads over time (m x n, one
column per time)
lambda
numeric vector of starting values for OD
flows (length k)
tol
numeric tolerance for halting iterations
Value
numeric vector of length k with estimated OD flows
