Why is the row space of a matrix important?I use it to define the rank of a matrix but are there other applications?

    The column space is very important: it tells you what the image of the corresponding linear transformation is. So transpose your matrices!2012-08-28

    The row space is also the orthogonal complement of the null space of the matrix.2012-08-28
