Final answer:
A non-symmetric matrix is a matrix in which the elements in its rows and columns are not symmetric with respect to the diagonal line. An example of a non-symmetric matrix is [1 2 3] [4 5 6] [7 8 9].
Step-by-step explanation:
A non-symmetric matrix is a matrix in which the elements in its rows and columns are not symmetric with respect to the diagonal line. In other words, if matrix A is non-symmetric, then Aij ≠ Aji for at least one pair of indices (i, j).
Here is an example of a non-symmetric matrix:
[1 2 3]
[4 5 6]
[7 8 9]
In this matrix, the element A12 (which is 2) is not equal to the element A21 (which is 4), making it non-symmetric.
