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

  
    
      
        M
        =
        
          
            [
            
              
                
                  0
                
                
                  0
                
                
                  0
                
              
              
                
                  0
                
                
                  0
                
                
                  0
                
              
              
                
                  0
                
                
                  0
                
                
                  0
                
              
            
            ]
          
        
      
    
    {\displaystyle 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

  
    
      
        
          
            
              v
              →
            
          
        
        =
        (
        0
        ,
        0
        ,
        0
        ,
        0
        )
      
    
    {\displaystyle {\vec {v}}=(0,0,0,0)}
