2.9: The Rank Theorem - Mathematics LibreTexts

A common approach to finding the rank of a matrix is to reduce it to a simpler form, generally row echelon form, by elementary row operations. Row operations do not change the row space (hence do not change the row rank), and, being invertible, map the column space to an isomorphic space (hence do not change the column rank). Once in row echelon form, the rank is clearly the same for both row rank and column rank, and equals the number of pivots (or basic columns) and also the … WebbExample 5: The Rank of a Matrix What value can 𝑘 not take if the rank of the matrix 𝐴 = 7 4 − 1 5 2 2 𝑘 − 2 4 − 9 1 5 − 2 1 is 3?
