Zero Matrix

A zero matrix is a matrix with all its entries being zero. An example of a zero matrix is

$M=\left[\begin{array}{ccc}0& 0& 0\\ 0& 0& 0\\ 0& 0& 0\end{array}\right]$

Zero Vector

A zero vector also called a null vector is a vector with all its entries being zero. An example of a zero vector is

$\overrightarrow{v}=(0,0,0,0)$
