The convert(A, Matrix) function converts A into a Matrix. This is accomplished by simply passing A and any additional parameters to the Matrix constructor.

$A≔\left[\left[1\,2\right]\,\left[3\,4\right]\right]$

$A≔\left[\left[1\,2\right]\,\left[3\,4\right]\right]$

$\mathrm{A1}≔\mathrm{convert}\left(A\,\mathrm{Matrix}\right)$

$\mathrm{A1}≔\left[\begin{array}{cc}1& 2\\ 3& 4\end{array}\right]$

$\mathrm{type}\left(A\,\mathrm{Matrix}\right)$

$\mathrm{false}$

$\mathrm{type}\left(\mathrm{A1}\,\mathrm{Matrix}\right)$

$\mathrm{true}$

$M≔\mathrm{matrix}\left(3\,3\,\left[\left[1\,1\,1\right]\,\left[1\,2\,3\right]\,\left[7\,8\,9\right]\right]\right)$

$M≔\left[\begin{array}{ccc}1& 1& 1\\ 1& 2& 3\\ 7& 8& 9\end{array}\right]$

$\mathrm{M1}≔\mathrm{convert}\left(M\,\mathrm{Matrix}\,\mathrm{datatype}=\mathrm{float}\right)$

$\mathrm{M1}≔\left[\begin{array}{ccc}1.& 1.& 1.\\ 1.& 2.& 3.\\ 7.& 8.& 9.\end{array}\right]$

$\mathrm{type}\left(M\,\mathrm{Matrix}\right)$

$\mathrm{false}$

$\mathrm{type}\left(\mathrm{M1}\,\mathrm{Matrix}\right)$

$\mathrm{true}$
