Chapter 2, Problem 22P
Create two row
(a) A vector (name it vDE) that contains the 2nd through the 5th elements of vD and the 4th through 7th elements of yE; i.e., vDE =24 28 32 36 59 62 65 68.
(b) A vector (name it vED) that contains elements 6. 5. 4. 3. and 2 of yE and elements 4, 3. 2, and 1 of vD; i.e., vED = 65 62 59 56 53 32 28 24 20.
In both parts use vectors to address the elements of vD and yE that are assigned to vDE and VED, respectively. Do not enter the elements of the vectors explicitly.
