Question details

To check that you have correctly entered these matrices into
Matlab, verify that

(a)  Let D = CBA^{T}. Find d_{24} (i.e., find the entry in row 2, column 4 of the matrix D) 
(b)  Let E = AB^{T}C^{T}. Find tr (E) 
(c)  Let F be the reduced row echelon form of A^{T}CB. Find f_{14}. (i.e., find the entry in row 1, column 4, of the reduced row echelon form of A^{T}CB). 
Answer must be in MATHLAB form
