Thanks, Marco. That is it. Cheers, Laurens
Well, in fact you do not even need the Flatten or Partition:
Select[# < 0 &] /@ list
Cheers,
Marco
Hi Laurens, The easiest I can think of is the following:
list = {{-1, 4, -5, 6}, {-5, -4, 3, 1}}; l1 = Flatten[list] // Select[# < 0 &]; Partition[l1, 2] {{-1, -5}, {-5, -4}}
