  • 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.
  • See also: Dimensions, Depth, VectorQ, MatrixQ.
