The function stackmatrix joins two or more matrices or vectors together vertically, where a vector is interpreted as a row vector. The matrices and vectors must have the same number of columns.

The command with(linalg,stackmatrix) allows the use of the abbreviated form of this command.

$\mathrm{with}\left(\mathrm{linalg}\right)\:$

$a≔\mathrm{matrix}\left(2\,2\,\left[1\,2\,3\,4\right]\right)$

$a≔\left[\begin{array}{cc}1& 2\\ 3& 4\end{array}\right]$

$b≔\mathrm{matrix}\left(2\,2\,\left[5\,6\,7\,8\right]\right)$

$b≔\left[\begin{array}{cc}5& 6\\ 7& 8\end{array}\right]$

$\mathrm{stackmatrix}\left(a\,b\right)$

$\left[\begin{array}{cc}1& 2\\ 3& 4\\ 5& 6\\ 7& 8\end{array}\right]$

$v≔\mathrm{vector}\left(2\,\left[1\,2\right]\right)$

$v≔\left[\begin{array}{cc}1& 2\end{array}\right]$

$\mathrm{stackmatrix}\left(v\,b\,v\right)$

$\left[\begin{array}{cc}1& 2\\ 5& 6\\ 7& 8\\ 1& 2\end{array}\right]$
