Greetings
A few weeks ago, there was much excitement here when
it was shown that one can get all the advantages of
MatrixForm output, without the disadavantages, by using:
MakeBoxes[m_?(Function[t,MatrixQ[Unevaluated[t]]&&(t=!={{}}),HoldAll]),
StandardForm] :=
RowBox[{"(", GridBox[Map[Function[t,MakeBoxes[t,StandardForm],HoldAll],
Unevaluated[m],{2}]],")"}]
____
Now suppose:
1) We switch the above ON.
2) Then, how do we switch it off for a particular function's ouptut.
That is, if MyFunc[x] returns a matrix, which we want formatted
as a List (and not in "Fancy Matrix" form), how can we switch
it off LOCALLY for this function's output only,
and without converting back to InputForm ?
Any ideas ? Anyone ?
Cheers
Colin
