Question 63Asked in DSSSB TGT Computer Science (Technical), 12 Sep 2025, Shift 3 (5:00 PM)

Which of the following options is true for a Hermitian matrix?

  1. Aaᵢⱼ = conj(aⱼᵢ) (aᵢⱼ equals the complex conjugate of aⱼᵢ)
  2. Baᵢⱼ = −aⱼᵢ
  3. Caᵢⱼ = aⱼᵢ
  4. Daᵢⱼ = −conj(aⱼᵢ)
Show answerHide answer

Correct answer: (A) aᵢⱼ = conj(aⱼᵢ) (aᵢⱼ equals the complex conjugate of aⱼᵢ)

Explanation

A Hermitian matrix equals its conjugate transpose, so aᵢⱼ = conj(aⱼᵢ). aᵢⱼ = aⱼᵢ is the rule for a symmetric matrix, and the minus forms are for skew types.
