Split
Split
[
list
]
splits
list
into sublists consisting of runs of identical elements.
Split
treats pairs of adjacent elements as identical whenever applying the function
test
to them yields
True
.
MORE INFORMATION
The default function used to test whether elements are identical is
SameQ
.
Split
can be used to perform run-length encoding.

Generalizations & Extensions
(5)
Split in increasing runs of elements:
Decreasing runs of elements:
Split based on first elements:
Split at jumps:
Split so that in each sublist successive elements are not the same:
