Riffle

gives

Riffle

gives

Riffle

yields a list in which every n

element is x.

Riffle

yields a list in which x appears if possible at positions

, ... ,

MORE INFORMATION

If there are fewer than gaps between in Riffle, the are used cyclically.

Riffle gives {e}.

The specification is of the type used in Take. Negative indices count from the end of the list.

Riffle is equivalent to Riffle.

Riffle is equivalent to Riffle.

In Riffle, if list and xlist are of the same length, then their elements are directly interleaved, so that the last element of the result is the last element of xlist.

Riffle works with SparseArray objects.
