WebFigure 1: Any matrix A of rank k can be decomposed into a long and skinny matrix times a short and long one. It’s worth spending some time checking and internalizing the equalities in (2). OK not quite: a rank-2 matrix is one that can be written as the sum of two rank-1 matrices and is not itself a rank-0 or rank-1 matrix. Rank-k Matrices. 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. cycloplegics and mydriatics
