Vector Space Span

TOPICS

Search

The span of subspace generated by vectors v_1 and v_2 in V is

Span(v_1,v_2)={rv_1+sv_2:r,s in R}.

A set of vectors m={v_1,...,v_n} can be tested to see if they span n-dimensional space using the following Wolfram Language function: 

  SpanningVectorsQ[m_List?MatrixQ] :=
    (NullSpace[m] == {})
