The shape of an array is a vector of lengths of the dimensions of the array. The shape function ⍴ returns the shape of its right argument array.
(⍬≡⍴)¨1 'A' ⍝ The shape of a scalar is the empty numeric vector ⍬
1 1
⍴'ABCDE' ⍝ The shape of a vector is a length-1 vector
5
⍴'ABC'∘.,1 2 3 4 ⍝ The shape of the matrix result of an outer product
3 4
⍴'ABC'∘.,1 2 3 4∘.×0J1 1J2 ⍝ Two consecutive outer products result in a cuboid
3 4 2
