Repeat

Generated from the engine's own definition: compute-engine's symbol, which we neither extend nor document by hand.

Produce a sequence by repeating a single value. With 1 argument, returns an infinite sequence; with 2 arguments (value, count), returns a finite list of count copies.

Examples

Basic #

Repeats a symbol ten times

live ↗

In$\mathrm{Repeat}(c, 10)$Out$\bigl\lbrack c, c, c, c, c, c, c, c, c, c\bigr\rbrack$

Scope #

A list of ten zeros

live ↗

In$\mathrm{Repeat}(0, 10)$Out$\bigl\lbrack0, 0, 0, 0, 0, 0, 0, 0, 0, 0\bigr\rbrack$

A list of ten ones, handy as a weight vector

live ↗

In$\mathrm{Repeat}(1, 10)$Out$\bigl\lbrack1, 1, 1, 1, 1, 1, 1, 1, 1, 1\bigr\rbrack$

Applications #

A symbolic length makes the repeat empty, so the dot stays unevaluated with an empty list

live ↗

In$\mathrm{Dot}(\mathrm{list}, \mathrm{Repeat}(1, \mathrm{Length}(\mathrm{list})))$Out$\mathrm{Dot}(\mathrm{list}, \bigl\lbrack\bigr\rbrack)$
