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.
