SpletStep 2: Multiply Matrix by its Inverse (Identity Matrix) If we want to check the result of Step 1, we can multiply our original matrix with the inverted matrix to check whether the result … Given a vector space V, there is a natural bilinear map V × V → F given by sending (v, φ) to the scalar φ(v). The universal property of the tensor product V ⊗ V automatically implies that this bilinear map is induced by a linear functional on V ⊗ V . Similarly, there is a natural bilinear map V × V → Hom(V, V) given by sending (v, φ) to the linear map w ↦ φ(w)v. The universal property of the tensor product, just as used previously, says that t…
