We assume that A is an m × n matrix, and we define the linear map f by f(x) = Ax as above. • The rank of an m × n matrix is a nonnegative integer and cannot be greater than either m or n. That is, rank ⁡ ( A ) ≤ min ( m , n ) . {\displaystyle \operatorname {rank} (A)\leq \min(m,n).} A matrix that has rank min(m, n) is said to have full rank; otherwise, the matrix is rank deficient. • Only a zero matrix has rank zero.
