Khan Academy: Linear Algebra: Rowspace and Left Nullspace

Curated by ACT

Video reviewing two fundamental subspaces of a matrix (null space and column space) and introducing two more (row space and left null space). Finds each of these subspaces for a specific 2x3 matrix and its transpose. Demonstrates that the rank of the transpose of a matrix is equaivalent to the rank of the original matrix. [23:18]
