n #4: A matrix with complex entires is called unitary if A" = A*, where A* is the conjugate transpose described in the Tutorial 4 file. Which of the following matrices are unitary? 1+i 1-1 1+i - 1+i (ii) 2 1-i -1-i Note: Testing matrices for equality is always subject to the usual innacuracies in floating point arithmetic. So for the purpose of this problem, you can consider two matrices to be equal if their entries agree to at least 4 decimal places. Warning! Don't forget the constants in front of each matrix. They are crucial for this problem. (A) (i) and (ii) only (B) (ii) only (C) (iii) only (D) (ii) and (iii) only (E) (i) only (F) (i) and (iii) only (G) none of them (H) all of them Problem #4: F Just Save Submit Problem #4 for Grading
