Transpose[] There is no native matrix in Mathematica. The only data native data structure is List[] (what you usually see and input between braces {...}.) However, List is infinitely nestable, and there are functions that understand that if you apply them to a list of lists all of equal length, the outer list is treated as a matrix (for example, Det[] or Dot[] or MatrixForm[]). This is hugely flexible, because these same functions treat any level of nesting of lists (of the right structure) as a high order tensor.
