Vector subspace notation question

  1. Oct 14, 2007 #1
    when dealing with vector subspaces, an example of a question asks:
    x=(a,a,b)T (T is really a superscript)
    is any vector in S, then...
    what does that T superscript notation mean? does that mean transpose?

    It means you should swap rows for columns, so that matrix/vector becomes a column vector.
