Question

What is $A^T$ in Matrix?

Answer 1

Transpose Matrix:

If $A$ is a matrix, then $A^T$ is a transpose of that matrix.

The transpose of a matrix is found by interchanging its rows into columns or columns into rows.

Example: $A=\left[\begin{array}{ccc}1& 2& 4\\ 2& 1& 3\end{array}\right]$

The transpose matrix of $A$ is,

$A^T=\left[\begin{array}{cc}1& 2\\ 2& 1\\ 4& 3\end{array}\right]$
