Using MATLAB or Octave

1. Create the following matrices:

       34  8  6                  8

x =  7   5  12          y =  5          z = 56  13  82  9

       9   3  23                 2

a. create a matrix "d" from the 3rd column of matrix "x"

b. combine matrix "y" and matrix "d" to create matrix "e", with 3 rows and 2 columns

c. combine matrix "y" and matrix "d" to create matrix "f", with 6 rows and 1 columns

d. create matrix "g" from matrix "x" and the first 3 elements of matrix "z", 4 rows and 3 columns
