THIS IS A DISCRETE MATH QUESTION

Suppose A = [1 0 1 0 1 1 1 1 0] and B = [0 0 1 1 1 0 0 1 0] Let matrix C be the meet of A and B, that is,. Which of the following statements is true A is symmetric B is symmetric C is symmetric

Solution

1.A is symmetric as A is equal to transpose of (A^T)

As a_ij = a_ji

2. B is not symmetric as a_ij is not equal to a_ji
