 In [[leading axis theory]], the [[cell shape]] of each k-[[cell]] in an array is a suffix of that array's [[shape]], while the [[frame]] is a [[prefix]] of the shape.
-[[Iverson notation]] included the notion of a suffix vector <math>\omega^j(n)</math> consisting of <math>n-j</math> zeros followed by <math>j</math> ones; such a vector could be used to produce a length-<math>j</math> suffix of a length-<math>n</math> vector using [[Compress]]. The earliest versions of [[APL\360]] adapted this notation by defining a suffix function <syntaxhighlight lang=apl inline>n ⍵ j</syntaxhighlight> before removing it in favor of [[Take]] with a negative left argument.
