The prod(M) function computes the product of elements in M.

The prod(M) or prod(M,1) creates a row vector of column products of the matrix.

The prod(M,2) creates a column vector of row products of the matrix.

$M≔\mathrm{Matrix}\left(2\,3\,'\mathrm{fill}'=12x^2{y}^3\right)\:$

$\mathrm{prod}\left(M\,1\right)$

$\left[\begin{array}{ccc}144x^4{y}^6& 144x^4{y}^6& 144x^4{y}^6\end{array}\right]$
