Calculate Reference Yield

1 2 3 |

`x` |
Integer, the simulation number |

`Asize` |
A matrix (dimensions nsim by nareas) with relative size of areas |

`nareas` |
The number of spatial areas |

`maxage` |
The maximum age |

`N` |
Array of the numbers-at-age in population. Dimensions are nsim, maxage, nyears, nareas. Only values from the first year are used, which is the current N-at-age. |

`pyears` |
The number of years to project forward. Equal to 'nyears' for optimizing for q. |

`M_ageArray` |
An array (dimensions nsim, maxage, nyears+proyears) with the natural mortality-at-age and year |

`Mat_age` |
An array (dimensions nsim, maxage, nyears+proyears) with the proportion mature for each age-class |

`Wt_age` |
An array (dimensions nsim, maxage, nyears+proyears) with the weight-at-age and year |

`V` |
An array (dimensions nsim, maxage, nyears+proyears) with the vulnerability-at-age and year |

`retA` |
An array (dimensions nsim, maxage, nyears+proyears) with the probability retained-at-age and year |

`Perr` |
A matrix (dimensions nsim, nyears+proyears) with the recruitment deviations |

`mov` |
An array (dimensions nsim, nareas, nareas) with the movement matrix |

`SRrel` |
A numeric vector nsim long specifying the recruitment curve to use |

`Find` |
A matrix (dimensions nsim, nyears) with the historical fishing effort |

`Spat_targ` |
A numeric vector nsim long with the spatial targeting |

`hs` |
A numeric vector nsim long with the steepness values for each simulation |

`R0a` |
A matrix (dimensions nsim, nareas) with the unfished recruitment by area |

`SSBpR` |
A matrix (dimensions nsim, nareas) with the unfished spawning-per-recruit by area |

`aR` |
A numeric vector nareas long with the Ricker SRR a values |

`bR` |
A numeric vector nareas long with the Ricker SRR b values |

`MPA` |
A matrix of spatial closures by year |

`maxF` |
A numeric value specifying the maximum fishing mortality for any single age class |

`SSB0` |
SSB0 |

`plusgroup` |
Integer. Default = 0 = no plus-group. Use 1 to include a plus-group |

`useCPP` |
logical - use the CPP code? For testing purposes only |
