Question

Define equal matrices. Give an example.

Answer 1

Two matrices are equal if and only if they have the same order and corresponding elements are identical.

Example: If A= $\left[\begin{array}{cc}2& 3\\ 2& 6\end{array}\right],B=\left[\begin{array}{cc}x& y\\ z& 6\end{array}\right]$

then A = B $\leftrightarrow$ x = 2 , y = 3, z = 2
