gives a list of the dimensions of expr.
gives a list of the dimensions of expr down to level n.
Details and Options
- expr must be a full array, with all the pieces of expr at a particular level having the same length. (The elements of expr can then be thought of as filling up a hyper‐rectangular region.)
- Each successive level in expr sampled by Dimensions must have the same head.
- For SparseArray and StructuredArray objects, Dimensions yields the dimensions of the corresponding ordinary lists.
