Note that in the above example, the order of matrix A is 2×3 and the order of its
transpose matrix AT is 3×2.
The idea may be taught with spatial presentation of the matrix supported by necessary
text material in Braille.
- Symmetric matrix
A matrix denoted as A is called a symmetric matrix if A = AT.
Eg. : If A = ⎟⎟
⎟
⎠
⎞

⎛
−

− −
3 5 6
2 4 5
1 2 3
Note that in the above mentioned matrix A = AT and hence A is a symmetric matrix.
The idea could be explained to the child with spatial presentation supported by
necessary text material in Braille.
