WebThe short answer is that a matrix corresponds to a linear transformation. To multiply two matrices is the same thing as composing the corresponding linear transformations (or linear maps ). The following is covered in a text on linear algebra (such as Hoffman-Kunze): This makes most sense in the context of vector spaces over a field. WebThen the matrix equation Ax = b has exactly one solution: x = A − 1 b . Proof Example(Solving a 2 × 2 system using inverses) Example(Solving a 3 × 3 system using inverses) The advantage of solving a linear system using inverses is that it becomes much faster to solve the matrix equation Ax = b for other, or even unknown, values of b .
