释义	singular 1 Singular An $m\\times n$ matrix $A$ with entries from a field is called singular if its rows or columns are linearly dependent. This is equivalent to the following conditions: 1. The nullity of $A$ is greater than zero ( $\\operatorname{null}(A)>0$ ). 2. The homogeneous linear system $A\\mathbf{x}=0$ has a non-trivial solution. If $m$ = $n$ this is equivalent to the following conditions: 1. The determinant $\\det(A)=0$ . 2. The rank of $A$ is less than $n$ .
