Anonymous Functions An anonymous function is a function that is not written in a M-file, rather is associated with a function handle. Anonymous functions work as regular functions, accepting inputs and returning outputs. As an example to create an anonymous function with the handle sqr which squares a number: >> sqr = @(x) x.^2; >> sqr(5) ans = 25 As seen above, to call an anonymous function we use the function handle and then pass the required variables. There can be as many input variables as required. Exercise 3 During each iteration of the for loop in Code Snippet 1 a new point of the solution is calculated by shifting the coordinate by a set amount and updating the corresponding y coordinate by moving along the slope field given by f(t,y). For this exercise you will edit the code snippet so that it uses an anonymous function to calculate the value of the slope field each time. Write an anonymous function with the handle f that takes two inputs t and y and outputs the value of the slope field at those coordinates f(t,y) corresponding to the ODE in either Exercise 2 or Exercise 1. Copy and paste your function here: Enter code Replace the line y (k+1)=y(k)+dt*(1-exp(-4*t(k))-2*y()); of code snippet 1 with Y(k+1)=y(k)+dt*f(t(k),y(k)); Your Euler's method code should still work. Check that it does before proceeding
