Gets isotope frequencies in as functions of time
Contents
Syntax
[tMd aA_out aD_out aG_out] = isotope (tTXd_, Md, p, nMO, aA_, aD_, aG_, odds_)
Description
Obtains the isotope frequencies of the chemical elements C, H, O and N in reserve and structure as function of time, given the trajectories of temperature and food density with the isotope frequencies in food.

Remarks
The theory of isotpe dynamics is discussed in Section 4.7 of the DEB book.
Example of use
See mydata_isotope, which also uses function otolith to get 13C in otoliths under all 9 choices of selection from total, anabolic or catabolic fluxes of dissipation and growth.
