Vector Division

In general, there is no unique matrix solution A to the matrix equation


Even in the case of y parallel to x, there are still multiple matrices that perform this transformation. For example, given y=2x=(2,4), all the following matrices satisfy the above equation:

 [2 0; 0 2],[-184 93; 72 -34],[134 -66; -68 36].

Therefore, vector division cannot be uniquely defined in terms of matrices.

However, if the vectors are represented by complex numbers or quaternions, vector division can be uniquely defined using the usual rules of complex division and quaternion algebra, respectively.
