The column space (or range) of a matrix A is the vector subspace spanned by its column vectors. The dimension of the column space (or the number of linearly independent column vectors) is the rank of the matrix. This linear algebra-related article contains minimal information concerning its topic. You can help the Mathematics Wikia by adding to it.
