Print matrix with determinant brackets

[PG]

Hi,

If I have

m = Matrix([ [ 1, 2 ], [ 3, 4 ] ])

how can I latex m so it is printed as a determinant:

\begin{vmatrix}

1 & 2\\ 

3 & 4

\end{vmatrix}

Many thanks in advance,

PG

You can subclass the LatexPrinter and override this method: https://github.com/sympy/sympy/blob/master/sympy/printing/latex.py#L1299 to create your custom printer.

Try using Determinant from sympy.matrices.expressions.
