Give an example for Z as a function of f(x) and t, and once again, explicitly specify what you mean by 'to present'.

Hello Adham,
I am assuming that you want to define a function of type – z(f(x), t).
So here, you are having a function ‘z’ that depends on f(x) and t. You can represent ‘z’ using an anonymous function with two input arguments – x and t.
Let’s consider an example –
z(f(x), t) = f(x)*t + t^2
and
f(x) = x^2 + 3*x + 4
You can define z and f as follows -
% Define the function f(x)
f = @(x) x^2 + 3*x + 4
% Define the function z(f(x), t)
z = @(x, t) t*f(x) + t^2;
% Evaluate the function Z at x = 2 and t = 3
z(2,3)
You may refer to the following link to know about the usage of anonymous functions - Anonymous Functions
