Question

Example 4.2

The next function takes two input arguments. It does not return any output arguments. It simply prints the sum of the inputs to the command window when it runs.
function report_sum(x, y)
%Usage:
% report sum(x,y)
% x, y numbers to be added
fprintf('The sum is tu\\', x + y)
end
Here, we have used the built-in fprintf function to print output to the screen. We will discuss this function in more detail in Section 7.5.

Answer 1

The provided example demonstrates a MATLAB function that sums two inputs and prints the result using fprintf, illustrating the mathematical principle of commutativity.

Step-by-step explanation:

The code snippet provided is an example of a MATLAB function that takes two input arguments (x and y) and prints their sum to the command window, using the fprintf function.

The operation performed by the function is addition, and it adheres to the commutative property, which states that the sum of two numbers remains the same regardless of the order in which they are added, such as 2 + 3 yielding the same result as 3 + 2. This illustrates a fundamental concept in mathematics known as commutativity.
