Question

If (i, j)th element of matrix A is 2+3i , what is the corresponding element in A* or conjugate of A.

• A. -2 - 3i
• B. 3 + 2i
• C. 2 - 3i
• D. 3 - 2i

Answer 1

The correct option is C

2 - 3i

By the term complex conjugate of a matrix, we mean that the sign of imaginary part of all the elements in the original matrix is reversed. i.e., if x + iy is the element in A, then x - iy would be the corresponding element in A*.
