Obtain the equilibrium numbers at length: LSD approach — get_equilibrium_numbers

Solve for equilibrium numbers at length using the length-structured dynamics (LSD) approach.

Usage

get_equilibrium_numbers_lsd(
  n_iter = 200,
  tau = 0.5,
  R0,
  U0 = 0,
  recruitment_size_sl,
  growth_ytrsll,
  M_ytrsl,
  selectivity_ytrsfl,
  legal_ytrsfl,
  retained_ytrsfl,
  handling_mortality_y
)

Arguments

n_iter: the number of iterations to loop over.
tau: the time step.
R0: the average recruitment.
U0: the initial exploitation rate.
recruitment_size_sl: the size at recruitment (cm) by sex.
growth_ytrsll: the growth matrix by year, season, region, and sex.
M_ytrsl: the natural mortality by year, season, region, sex, and length.
selectivity_ytrsfl: the selectivity by year, season, region, sex, fishery, and length.
legal_ytrsfl: legal status by year, season, region, sex, fishery, and length.
retained_ytrsfl: legal status by year, season, region, sex, fishery, and length.
handling_mortality_y: legal status by year, season, region, sex, fishery, and length.

Value

a array of the initial numbers in the population by region, sex, and length.
