get_pars_h
Obtains parameters from growth data at multiple food levels
Contents
Syntax
[par, U] = get_pars_h (p, w, par0)
Description
Obtains parameters from growth data at multiple food levels. Maturity and somatic maintenance rate coefficients might differ.
Input
- p: (n,4)-matrix with quantities (n > 1). The columns are:
1 f % - % scaled functiomal response
2 L_b % mm % length at birth
3 L_i % mm % ultimate length
4 \dot{r}_B % d^-1 % von Bertalanffy growth rate* w: optional (n,3)-matrix with weight coefficient (default is ones) * par0: optional (6,1 or 2)-matrix with initial estimate for par
Output
- par: (5,1 or 2)-matrix with in the first column
1 VHb % d mm^2 % scaled maturity at birth: M_H/ ((1 - kap) {J_EAm})
2 g % - % energy investment ratio
3 kJ % d^-1 % maturity maintenance rate coefficient
4 kM % d^-1 % somatic maintenance rate coefficient
5 v % mm/d % energy conductance
a second column has ones (iterate) or zeros (fix)- U: (n,2)-matrix with U^0 = M_E^0/\{\dot{J}_{EAm}\}, U^b = M_E^b/\{\dot{J}_{EAm}\}
Remarks
Function <iget_pars_h.html *iget_pars_h* is inverse.
