copy : truefalse

Indicates whether a new rtable should be allocated when converting from other rtable types such as Array or Vector. The default is false, meaning that convert will attempt to provide a reference to the existing rtable instead of allocating a new one.

format : string

A string corresponding to one of the file formats described in Formats. The input expr will be decoded using the specified format and the data returned as a Matrix. If the format specified is not one for which a Matrix is a valid output type, an error is issued.

sourceformat : string

A synonym for the option format for consistency with other convert subroutines.

Any other options specified will be passed to the Matrix constructor.

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.

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

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

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

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

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

$\mathrm{false}$

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

$\mathrm{true}$

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

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

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

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

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

$\mathrm{false}$

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

$\mathrm{true}$

$\mathrm{convert}\left(''1,2,3\backslash n4,5,6\backslash n7,8,9''\,\mathrm{Matrix}\,\mathrm{sourceformat}=''CSV''\right)$

$\left[\begin{array}{ccc}1& 2& 3\\ 4& 5& 6\\ 7& 8& 9\end{array}\right]$

The convert/Matrix command was updated in Maple 2022.

The copy, format and sourceformat options were introduced in Maple 2022.
