Linear Algebra/Zero Matrices and Zero Vectors/

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

$$M = \begin{bmatrix} 0 & 0 & 0 \\ 0 & 0 & 0 \\ 0 & 0 & 0 \end{bmatrix}$$

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

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