The call scalarmul(A, expr) returns the matrix or vector which is the result of multiplying every entry in A by the scalar value expr.

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

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

$\mathrm{scalarmul}\left(\mathrm{array}\left(\left[\left[1\,2\right]\,\left[3\,4\right]\right]\right)\,2\right)$

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

$\mathrm{scalarmul}\left(\mathrm{array}\left(\left[1\,2\,3\,4\right]\right)\,3\right)$

$\left[\begin{array}{cccc}3& 6& 9& 12\end{array}\right]$

$v≔\mathrm{vector}\left(4\,\left[2\,x\,6\,-3\right]\right)$

$v≔\left[\begin{array}{cccc}2& x& 6& \mathrm{-3}\end{array}\right]$

$\mathrm{scalarmul}\left(v\,x\right)$

$\left[\begin{array}{cccc}2x& x^2& 6x& -3x\end{array}\right]$

$\mathrm{scalarmul}\left(\mathrm{transpose}\left(v\right)\,x\right)$

$\mathrm{transpose}\left(\left[\begin{array}{cccc}2x& x^2& 6x& -3x\end{array}\right]\right)$
