Question

What is the dimensionality of the set of all bisymmetric matrices of size n?

Answer 1

Let A denote the space of symmetric (n×n) matrices over the field K, and B the space of skew-symmetric (n×n) matrices over the field K. Then dim(A)=n(n+1)/2 and dim(B)=n(n−1)/2.

Answer 2

Answer:

Step-by-step explanation:

Let A denote the space of symmetric (n×n) matrices over the field K, and B the space of skew-symmetric (n×n) matrices over the field K. Then dim(A)=n(n+1)/2 and dim(B)=n(n−1)/2.
