get_tb1
Obtains scaled age at birth
Contents
Syntax
[tb lb uE0 info] = get_tb1 (p, eb, lb0)
Description
Obtains scaled age at birth, given the scaled reserve density at birth. Divide the result by the somatic maintenance rate coefficient to arrive at age at birth. Warning: this routine integrates backwards over maturity; the accuracy can be low
Input
- p: 1 or 3-vector with parameters g, k, v_H^b
Last 2 values are optional in invoke call to get_lb
- eb: optional scalar with scaled reserve density at birth (default eb = 1)
- lb: optional scalar with scaled length at birth (default: lb is obtained from get_lb)
Output
- tb: scaled age at birth \tau_b = a_b k_M
- lb: scalar with scaled length at birth
- uE0: scalar with scaled reserve at birth
- info: indicator equals 1 if successful, 0 otherwise
