its been kind of confusing for me, so I just wanted to confirm that: the rank of a matrix = the dimension of a column space = pivot of the column space but they do not equal the dimension of the space that the matrix is a subspace of (i.e. a 3x4 matrix whose column space is a subspace of R^3 but may have a rank of 2...
