TensorRank

TensorRank[expr] gives the depth to which expr is a full array, with all the parts at a particular level being lists of the same length.

TensorRank[list] is equivalent to Length[Dimensions[list]].

Examples: TensorRank[a,b] ; TensorRank[a,b] .

TensorRank[expr, n] tests only down to level n.

See The Mathematica Book: Section 3.7.11.
