Solution 1

The matrix (A + A^T) is called a Symmetric matrix.

Here's why:

A symmetric matrix is defined as a matrix that is equal to its transpose. If A is any given matrix, A^T denotes the transpose of matrix A.

The transpose of a matrix is achieved by flipping it over its diagonal, swapping the row and Knowee AI is a powerful AI-powered study tool designed to help you to solve study problem.
