Question 1 15 0 21 13 Consider the following matrix, A = 1 2 18 4 11 22 1 3 7 14 13 9 19 21 25 5 101 3 6 17 20 113 1. From A, generate the matrix B = [123 7 19 14] 21) [20 2. From A, generate the matrix C = 6 110 25 13 1 11] 1 15. 3. Generate a matrix D obtained by switching in the same time the first and second column, and the second and third row of A. 4. Generate form A the vector E=[13 13 15 20 21] 5. Use special matrices of MATLAB to generate the following matrix (from A): 2 0 1 3 10 21 2 7 14 3 F= 2 2 9 6 18 4 19 2 17 11 22 25 5 2 1
