calc_eqdist: Equilibrium distribution from movement matrix

In multiSA: Multi-Stock Assessment

Equilibrium distribution from movement matrix

Description

Applies the seasonal movement matrices several times in order to obtain the equilibrium spatial distribution over the course of a year. Not used in the model but useful for reporting.

Usage

calc_eqdist(
  x,
  nm = dim(x)[1],
  nr = dim(x)[2],
  start = rep(1/nr, nr),
  m_start = 1L,
  nit = 20
)

Arguments

x	Movement array ⁠[m, r, r]⁠. The second dimension corresponds to origin (sum to 1), and third dimension corresponds to destination
nm	Number of seasons
nr	Number of regions
start	The initial distribution. Vector of length nr
m_start	Integer, the season in which to apply the initial distribution and start the projection
nit	Integer, the number of times the movement matrix will be applied

Value

Matrix by season and region ⁠[m, r]⁠
