Determined number r, that is, the largest order among the non-zero minor determinants of

A, is called the rank of A.
Accordingly, there exists in a matrix of rank r at least one non-zero minor determinant of order r,

while all minor determinants of order higher than r, if present, vanish.
Obviously, the rank of a matrix A does not change if you alter arbitrarily the sequence of its rows

and columns, for the set of the minor determinants remains the same apart from changes in sign.

Rank of a null matrix is zero !!!!!
