WebProof of 'only-if' part Let rank ( A) = n. Since RREF ( A) is row-equivalent to A , RREF ( A) = R A, where R is an invertible matrix. Since rank ( A) = n, all rows of RREF ( A) = R A are non-zero. Since R A is a square matrix in RREF, R A = I n . Since R is invertible, all left inverses of R are the same as all right inverses of R . Web13 dec. 2024 · A is an 𝑛 × 𝑚 matrix.
