Add row/column algebra methods to Matrix for Vector

[Aweptimum]

Forgot to mention I might have the time to implement this myself next Friday if you approve of the feature

Hi @Aweptimum,

Thank you for your interest in MathPHP.

If I understand the request, it would be something like a new Matrix function called columnAddVector that:

• GIVEN a matrix
• AND a column
• WHEN the vector is added to a specific column of the matrix
• THEN the result is a new matrix with the specified column being the column sum, and the rest of the matrix unchanged.

Example

    | 1 1 1 |       | 1 |
M = | 2 2 2 |   V = | 2 |
    | 3 3 3 |       | 3 |

$R = $M->columnAddVector(0, $V);

    | 2 1 1 |
R = | 4 2 2 |
    | 6 3 3 |

And there would be equivalent ones for a row add as well.

Does that capture the intent of the feature request?

Yes, it captures it perfectly 👍
