A Real Number Matrix is a matrix whose matrix elements consist entirely of real numbers.

**Context:**- It can range from being a Positive Real Matrix to being an Non-Negative Real Matrix to being a Non-Positive Real Matrix to being a Negative Real Matrix.
- It can range from being a Dense Real Number Matrix to being a Sparse Real Number Matrix.
- It can range from being a Square Real Number Matrix to being a Non-Square Real Number Matrix.
- It can range from being a 2D Real Matrix to being a 3D Real Matrix to being ...

**Example(s):**- [math]\displaystyle{ \begin{bmatrix}1.34 & -1/9 & 13.1 \\20.0 & 55.1 & 0 \end{bmatrix}. }[/math]

**Counter-Example(s):**- an Integer Matrix.
- a Binary Matrix.
- a Complex Number Matrix,.
