EXERCISE 1 Enter the following matrices and vectors in MATLAB -9 A= 7 -5 2 8 -9 -9 B= -7 14 9 b= -8 14 -8 -8 -6 -3 4 2 -6 -14 32 C= [ 3 3 2 ], d= 7 . -1 2 (a) Perform the following operations: AB, BA, CA and Bd (use standard linear algebra multiplication). (b) Construct a 6 x 3 matrix C= A B and a 3 x 4 matrix D= (B d]. (c) Use the backslash command to solve the system Ax = b. (d) Replace (3,3)-entry of the matrix A by 0. (e) Extract the 2nd row of the matrix A and store it as a vector a. (f) A row or a column of a matrix can be deleted by assigning the empty vector [] to the row or the column; (for instance A(2,:)=[] deletes the second row of the matrix A). Delete the third column of the matrix B
