Struggling with "function handle". What is "specifiy as function handle"??

Recall the optimization model of maximizing the profit P(t) = p(t)w(t) C(t) from the sale of a pig with weight w(t) in pounds, price p(t) in dollars per pound, and cost of keeping the pig C(t) up to time t in dollars. 5. Write a MATLAB script that uses anonymous functions and the fzero command (or your Newton's method function) to solve the pig selling problem. Specify p(t), w(t), and C(t) along with p'(t), w'(t), and C"(t) at the beginning of the file as function handles and then find t so that p'(t)w(t) +p(t)w'(t) C'(t) = 0. Hint: you will need an anonymous function that combines your other functions like dPdt = @(t) pp(t)*w(t) + p(t)*wp(t) - Cp(t) =
