Let x = [3, 2, 6, 8]' and y [4, 1, 3, 5]' Write Matlab commands that perform the following tasks (NB. x and y should be column vectors). = a. Add the sum of the elements in x to y (use the sum function). b. Raise each element of x to the power specified by the corresponding element in y. Divide each element of y by the corresponding element in x. C. d. Multiply each element in x by the corresponding element in y, calling the result z. e. Find the sum of the vector z and assign the result to a variable called w. f. Compute x' *y - w.
