Hi,
and what does
f1[{x1_, x2_}] := Block[{L}, L = {x1, 1 - x1};
Print[L];(*Print prints {x1,1-x1} but I want to get value {.5, .5)*)
];
and is Block[{},___] not nonsense ? because if you don't
have local variabels you don't need a block and
f1[{x1_, x2_}] := Print[{x1,1-x1}]
would do it as well?
Regards
Jens
