**Name:**

Dimensions - determine dimenstions of a (hyper-rectangular) SLI array

**Synopsis:**

[array] Dimensions -> [d1 d2 ... dn]

**Examples:**

SLI ] [1 2 3] Dimensions -> [3]

SLI ] [[1 2 3] [4 5 6]] Dimensions -> [2 3]

SLI ] [[[1 2][3 4]][[5 6][7 8]]] Dimensions -> [2 2 2]

**Description:**

Dimensions corresponds to the Mathematica function of

the same name. It takes a sli array and returns a list with

dimensions [d1 d2 ... dn] where di gives the dimension of the

array at level i.

The length of the dimensions-list corresponds to the TensorRank of

the array.

**Remarks:**

Dimensions assumes that the array is hyper-rectangular

(rectangle,cuboid, ...), i.e., all subarrays at a given level

have the same number of elements.

Dimensions does not check, if the array really is hyper-rectangular. It

will not fail if this is not the case. Instead, the dimensions

that are returned correspond to the number of elements of the

first subarray in each level.
