Hi everyone,

How can I get three columns from a list?

{{{0, 0, 0.}, {1, 0, 0.841328}, {2, 0, 0.90933}, {3, 0,
0.141288}}, {{0, 1, 0.}, {1, 1, 0.256389}, {2, 1, 0.536549}, {3, 1,
0.410589}}, {{0, 2, 0.}, {1, 2, 0.054223}, {2, 2, 0.230078}, {3,
2, 0.309327}}, {{0, 3, 0.}, {1, 3, 0.00783825}, {2, 3,
0.0771227}, {3, 3, 0.163252}}}

@zhk Well, yes, but that's because you have an Nx3 array. What do you mean by column, then?

Minimize[Norm@p, p \[Element] BooleanRegion[Not, {DiscretizeRegion@Ball[]}]]

(* {6.93629*10^-11, {p -> {-4.21234*10^-11, 3.62133*10^-11, -4.15382*10^-11}}} *)

Another day, another oddball bug.

@Edmund what do you mean by Mathematica Online? If it's the cloud and you have cloud notebooks you can share via the Permissions option to the CloudObject.
