Something like this?
(%i1) [[1, 2], [3, 4]];
(%o1) [[1, 2], [3, 4]]
(%i2) apply(matrix, %);
[ 1 2 ]
(%o2) [ ]
[ 3 4 ]
The trick is that matrix is a function that takes rows as (a variable
number of) arguments, so we need to convert
[[1, 2], [3, 4]]
to
matrix([1, 2], [3, 4])
Fortunately, that's exactly what apply does!
