Question

For a matrix M = ( mj]; ij = 1,2,3,4, the diagonal elements are all zero and mij = -mij. The minimum number ofelements required to fully specify the matrix is(A) 0(B) 6(C) 12(D) 16​

Answer 1

Answer:

I didn't understand your question

Answer 2

Answer:

As given in question, it 4*4 matrix with diagonal matrix = 0. So no of non diagonal matrix=12 (6+6)

Now, as Mij=-Mji, which is the property of skew-symmetric matrix.

So, only half of the 12 will be sufficient to complete the matrix.
