Exercise 1.7 Using the commands introduced above, construct a new matrix with whatever name you like from Fibonacci that consists of the elements in the last two rows and the middle two columns of Fibonacci. (The result should therefore be a 2x2 matrix.) Be sure to include the command you used and the resultant output in your Word document.

We often wish to take a matrix that we have defined and have MATLAB tell us information about it. For example, maybe we want to know what number is in the third row and fourth column, or maybe we want to view the whole fifth row. These tasks are done with regular parentheses, ( and ). Example 1.3 To see the (1, 2) entry of the matrix A above (that is, the entry in the first row and second column), we use the command >> A (1, 2) We can also use the colon: to mean "all," as in the command >> A (2, :) which will give us the entire second row of the matrix A. The colon can also be used to represent a range of rows or columns: the command >> Fibonacci (2:4,1) will give us the entries of Fibonacci from the second through fourth rows in the first column.
