Which of the following statements is NOT CORRECT.
- A A row matrix has only one row.
- B A diagonal matrix has all diagonal elements equal to zero.
- C A symmetric matrix is a square matrix satisfying certain conditions.
- D A skew-symmetric matrix has all diagonal elements equal to zero.
Answer & Solution
Correct Answer
(B) A diagonal matrix has all diagonal elements equal to zero.
Step-by-step Solution
Detailed explanation
A diagonal matrix has all non-diagonal elements equal to zero. Its diagonal elements can be non-zero. Therefore, the statement "A diagonal matrix has all diagonal elements equal to zero" is NOT CORRECT.
