A Non-Negative Matrix is a matrix whose values are non-negative (composed of non-negative vectors).

• Context:
  • It can range from being a Square Non-Negative Matrix to being a Non-Square Non-Negative Matrix.
  • It can range from being a Non-Negative Integer Matrix to being a Non-Negative Real Matrix.
• Example(s):
  • [math]\displaystyle{ \begin{bmatrix}1 & 9 & 0 \\0 & 55 & 6 \end{bmatrix} }[/math].
  • a Positive Matrix.
  • …
• Counter-Example(s):
