Important: The linalg package has been deprecated. Use the superseding command LinearAlgebra[Minor], instead.

- For information on migrating linalg code to the new packages, see examples/LinearAlgebraMigration.

The function minor returns the (r,c)th minor of the matrix A.  This is the matrix obtained by removing the rth row and the cth column of A.

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

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

$A≔\mathrm{matrix}\left(3\,3\,\left[1\,5\,2\,6\,3\,7\,4\,8\,5\right]\right)$

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

$\mathrm{minor}\left(A\,2\,2\right)$

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