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.
