# Right Matrix Division

Right Matrix Division (B/A) is defined as solving the solution 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 = A*inv(B) is used to solve the solution. If A is over determined, the least squares solution is produced. If A is underdetermined, then a least squares solution with the maximum number of zeros 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. | ||

Matrix | 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. | x = B/A solves xA = B using right matrix division. |
