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.
