... (4 points) We’ve seen that one basis for C(A) is formed by taking the columns of A that correspond to the pivot-columns of rref(A). Thus, {a1 , a2 , a4 } is a basis for C(A). From this, it immediately follows that dim C(A) = 3 and therefore no set of size 1, 2, or 4 can ever be a basis for C(A); we ...

Basis (linear algebra)
Basis vector redirects here. For basis vector in the context of crystals, see crystal structure. For a more general concept in physics, see frame of reference.A set of vectors in a vector space V is called a basis, or a set of basis vectors, if the vectors are linearly independent and every vector in the vector space is a linear combination of this set. In more general terms, a basis is a linearly independent spanning set.Given a basis of a vector space V, every element of V can be expressed uniquely as a linear combination of basis vectors, whose coefficients are referred to as vector coordinates or components. A vector space can have several distinct sets of basis vectors; however each such set has the same number of elements, with this number being the dimension of the vector space.
