Row Vector
From the book
Chapter 2: Matrix. In the chapter mind map this icon labels Row vector. The discussion below is excerpted and lightly edited from § Definition: Matrix as Horizontal Stack of Column Vectors in Mathematics for AI and Machine Learning.
Given column vectors $\mathbf a_0, \ldots, \mathbf a_{N-1} \in \mathbb{R}^{M \times 1}$ the matrix is formed by horizontally stacking these vectors.
