1 Construct two matrices of integers, A with dimensions 3x3 and B with dimensions 3x1. Find the product AxB. Also find the product A.*B(2). What happens when you try A.*B or B*A?

2 Get the second row of A. Get the third column of A. Interchange the second and third row of A. Arrange the columns of A in reverse order (col 3, col 2, col 1).

3Construct the 3x3 identity matrix I3. Find I3*A.

4 Find the eigen values and eigen vectors of A.

5 Construct a 3x3 matrix of integers, C. Try A.*C, A*C and C*A. Now do A./C, A/C, A\C, C\A and inv(A).
