6. (5 marks) Write the MATLAB commands that create the following matrix by using shorthand methods for creating vectors with constant spacing. Do not type individual elements explicitly. A 3 20 12 1-2 5 16 12.8 -3 7 12 13.6 -4 9 8 14.4 -5 11 4 15.2 -6 13 0 16 --7) . Then, do the following: Create a variable x by assigning the value in the 4"row and 3 column of A to s. Do not type the value explicitly. Create a row vector X4 by assigning the 4" row of A to X4. Do not type the values explicitly Create a 2 x 3 matrix named M that contains the elements of A in the Pal and 3 mows, and the 4 to 6 columns. Do not type the values explicitly
