22. Create two row vectors vD=20:4:44 and vE=50:3:71. Then, create the following new vectors by assigning elements of vD and vE to the new vectors:

(a) A vector (name it vDE) that contains the 2nd through the 5th elements of vD and the 4th through 7th elements of vE; 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 vE 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 vE that are assigned to vDE and vED, respectively. Do not enter the elements of the vectors explicitly.
