WebYou can generalize the calculation in Example 3.7 to prove that the dimension of dimMn × m(R) and Mn × m(C) is nm. Suppose V is a one-dimensional F -vector space. It has a basis v of size 1, and every element of V can be written as a linear combination of this basis, that is, a scalar multiple of v. So V = {λv: λ ∈ F}. Webminimum number of elements needed to build the space V with linear combinations. The following lemma, which we will use in proving the proposition, captures this idea that a basis is more minimal than a general spanning set might be: Lemma If S ˆV is a nite set and B ˆSpanS is a linearly independent set, then jBj jSj.
