Question

What is transpose means?

Answer 1

Transpose:

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

A transpose matrix of a matrix $A$ is denoted by $A^T$.

Example: If $A=\left[\begin{array}{ccc}1& 2& 3\\ 2& 5& 4\end{array}\right]$, then the transpose matrix is $A^T=\left[\begin{array}{cc}1& 2\\ 2& 5\\ 3& 4\end{array}\right]$
