Write a MATLAB function which computes the cumulative product of the elements in a vector. The cumulative product of the jth element of the vector x, xj, is defined by pj = (x1)(x2) ... (xj) for j = 1:length of the vector x. Create 2 different versions of this function. a. One that uses two for-loops to explicitly carry out the calculations, element by element. An "inner" loop should accumulate the product and an "outer" loop should move through the elements of the vector p. b. One that uses the built-in function prod to replace the inner loop.
