Enter the following 3 matrices into Matlab, A= 11 24 -12 46 -9 16 -6 -33 -20 -36 42 43 27 11 33 5 44 26 -25 B = -48 38 -38 -21 -12 -20 -28 24 17 42 30 -30 C=-46 19 -23-42 44 -16 To check that you have correctly entered these matrices into Matlab, verify that 69708 -70142 4580645327 -66468 50644 A'CB -53860 -27120 109596 9554 147166 -47553 and that tr (ACB) = 363869 127968 -142018 75778 96351 (a) Let D=CBA" Find ds, c.c., find the entry in row 5,column 1 of the matrix D) (b) Let E = AB'C'. Find tr(E) (e) Let F be the reduced row echelon form of ACB. Find 14 (i.e., find the entry in row 1 column 4, of the reduced row echelon form of A'CB)
