get_ael
Gets age, reserve and length at birth
Contents
Syntax
[aEL E0 lb] = get_ael (par, F)
Description
Obtains state variables at age zero and at birth from parameters and scaled reserve density at birth.
Input
- par: 8-vector with parameters:
1 {J_EAm}, mol/d.cm^2, max spec assimilation rate
2 kap, -, allocation fraction to soma
3 v, cm/d, energy conductance
4 [J_EM], mol/d.cm^3 spec somatic maintenance
5 k_J, 1/d, maturity maintenance rate coefficient
6 y_VE, mol/mol, yiles of structure on reserve
7 M_H^b, d.cm^2, scaled maturity at birth
8 [M_V], mol/cm^3, vol-spec mass of structure- F: n-vector with scaled functional responses
Output
- aEL: (n,3)-matrix with a_b, M_E^b, L_b
- E0: n-vector with M_E^0
- lb: n-vector with L_b/ L_m
Remarks
The output values are numerically obtained, starting from the values for a foetus; the age at birth of this foetus must again be obtained numerically, which is done starting from the assumption kJ/ kM = (1 - kap)/ kap, which gives a constant maturity density mH = yEV (1 - kap)/ kap. See get_ael_f for foetuses, which differ from eggs by not being limited by reserve availability.
