Mathematica one-liners

• Visualize a block matrix mat

  MatrixForm[{Grid[Map[Grid, mat, {2}], Dividers -> Center]}]

performance notes

• In prototyping, you may use something like

  expr[#]&/@list

  where expr[#] merely stands for an expression containing #. If you don't need the pure function expr[#]& else where, you may rewrite this as

  Table[expr[elem], {elem, list}]

  This will remove an overhead from pure function calling.
