Chapter 2, Problem 34P

Create the following vector A.

A= [1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18]

Then using the MATLAB’s built-in reshape function create the following matrix B from the vector A:

$B=\left[\begin{array}{cccccc}1& 4& 7& 10& 13& 16\\ 2& 5& 8& 11& 14& 17\\ 3& 6& 9& 12& 15& 18\end{array}\right]$

By writing one command and using the colon to address range of elements (do not type individual elements explicitly), use the matrix B to:

1. Create a nine-element column vector named Ba that contains the elements of the first, third, and fifth columns of B.
2. Create a seven-element row vector named Bb that contains elements 2 through 5 of the second row of B and the elements of the third column of B.
3. Create a six-element row vector named Be that contains elements 3 through 5 of the first row, and elements 2 through 4 of the third row of B.
