# Right Matrix Division

Right Matrix Division (B/A) is defined as solving the equation xA = B.

Depending on whether A is square, under determined, or over determined, the way to solve
this solution is different. When A is square, `x = B*inv(A)`

. If A is over
determined, the least squares solution is produced. If A is underdetermined, the least
squares solution with the minimum norm is produced.

/ | Scalar | Row Vector | Column Vector | Matrix |
---|---|---|---|---|

Scalar | Divides the first by the second scalar. | x = B/A solves xA = B using right matrix division. | ||

Row Vector | Divides each index of the row vector by the scalar, resulting in a row vector the same size as the original vector. | x = B/A solves xA = B using right matrix division. | x = B/A solves xA = B using right matrix division. | |

Column Vector | Divides each index of the column vector by the scalar, resulting in a column vector the same size as the original vector. | x = B/A solves xA = B using right matrix division. | ||

## Examples

```
3 / 2
ans =1.5
[6 4 2] / 3
ans = [2 1.3333 0.6667]
[5 4 3] / [4 6 3]
ans = 0.86885
