The counter in a for or while loop can have an explicit increment: for i=m:k:n. This advances the counter i by increment k each time. In this problem we will evaluate the product of the first 9 even numbers 2·4·6·...·18 in two ways: (a) Write a script file that evaluates the product of the first 9 even numbers using a for loop.(b) Evaluate the product of the first 9 even numbers using a single MATLAB command. Use the MATLAB command prod.
