Need help in varying input and using conditional statement in code

Hi, I have been running my code with different initial values for many runs but it is very rigorous work to find the optimum set of values.I want to check my code for varying input parameters/- Q(varying monthly),N(1),P(1),TIC(1). Also, I want to put a conditional statement for N/P and C/N in the code to change the formula as per scenario. Can you guide me in right direction?

Please comment on:

• t is passed as input argument in all six anonymous functions. However, t isn't used in any of them.
• P and TIC are used in the anonymous function named X. However, they are not passed as input argument. Thus, the values of P and TIC at the time of the creation of the functions will be used. Is that by intent?
• N and TIC are used in the anonymous function named Y. However, they are not passed as input argument. Thus, the values of N and TIC at the time of the creation of the functions will be used. Is that by intent?
