Question

A square matrix X is non singular if

Answer 1

Answer:

Step-by-step explanation:A non-singular matrix is a square one whose determinant is not zero. The rank of a matrix [A] is equal to the order of the largest non-singular submatrix of [A]. It follows that a non-singular square matrix of n × n has a rank of n. Thus, a non-singular matrix is also known as a full rank matrix.
