Let A 4 15 2 14 12 9 8 6 1 3 7 16 10 11 5 13 its a 4x4 Prov

Let A =

4, 15, 2, 14

12, 9 ,8, 6

1, 3, 7, 16

10, 11, 5, 13

(it\'s a 4x4)

Provide a Matlab expression that yields B =

12, 9, 8, 6

1, 3, 7, 16

For example, the expression B = A(1:2, 1:2) gives B = 4 15

12 9

Solution

The matlab code is:

A =[4,15,2,14;12,9,8,6;1,3,7,16;10,11,5,13]
B = A(2:3,[1:4])
