Step 1 ：First, find the minimum of each row in the matrix.

Step 2 ：For the first row, the minimum is \(4\).

Step 3 ：For the second row, the minimum is \(-3\).

Step 4 ：For the third row, the minimum is \(4\).

Step 5 ：Next, find the maximum of each column in the matrix.

Step 6 ：For the first column, the maximum is \(4\).

Step 7 ：For the second column, the maximum is \(4\).

Step 8 ：For the third column, the maximum is \(9\).

Step 9 ：The intersection of the row minimum and column maximum gives us the saddle points. In this case, we have two saddle points: \((1,1)\) and \((1,2)\) where the value is \(4\), and \((3,3)\) where the value is \(9\).

Step 10 ：For the second part, again find the minimum of each row in the matrix.

Step 11 ：For the first row, the minimum is \(6\).

Step 12 ：For the second row, the minimum is \(1\).

Step 13 ：For the third row, the minimum is \(6\).

Step 14 ：Then, find the maximum of each column in the matrix.

Step 15 ：For the first column, the maximum is \(6\).

Step 16 ：For the second column, the maximum is \(9\).

Step 17 ：For the third column, the maximum is \(6\).

Step 18 ：For the fourth column, the maximum is \(16\).

Step 19 ：The intersection of the row minimum and column maximum gives us the saddle points. In this case, we have one saddle point: \((1,1)\) where the value is \(6\).

Step 20 ：So, the final answer is \(\boxed{\text{Saddle points are (1,1), (1,2) with value 4, (3,3) with value 9 for the first matrix and (1,1) with value 6 for the second matrix.}}\)
