I am using a vector whose length I want to vary. So supposing the vector is x = [f(1), f(2), f(3), ..... f(n)]. How do I find the product of all these entries multiplied with each other? I don't want to use cumprod because it gives me a vector output, but I only want the scalar output where the final answer is a product of all the entries.

Use the prod function
theProduct = prod(yourVector);
