Problem #1: Enter the following 3 matrices into Matlab, Problem #1(a): Problem #1(b): Problem #1(c): A = -18 -2 13 -35 -24 45 8 7 38 -2 -37 -28 -14 -29 -31 -16, B= 12 -12 -4 -34 10 19 C = 26 -8 -32 35 -21 -7 38 -18 -27 -13 -2 10 1 To check that you have correctly entered these matrices into Matlab, verify that ATCB= -34953 67676 -22412 -11337 -20706 1866 63126 -102582 36270 -21487 -14736 -1712 73783 -2493 -121086 10457 and that tr (ACB) = -8932. (a) Let D=CBAT. Find d51 (i.e., find the entry in row 5, column 1 of the matrix D) (b) Let E=ABTCT. Find tr (E) (c) Let F be the reduced row echelon form of ATCB. Find f14. (i.e., find the entry in row 1, column 4, of the reduced row echelon form of ATCB).
