SplitBy

SplitBy(list, f)

splits list into collections of consecutive elements that give the same result when f is applied.

Examples

>> SplitBy(Range(1, 3, 1/3), Round)
{{1,4/3},{5/3,2,7/3},{8/3,3}}
{{1, 4 / 3}, {5 / 3, 2, 7 / 3}, {8 / 3, 3}}

>> SplitBy({1, 2, 1, 1.2}, {Round, Identity})
{{{1}},{{2}},{{1},{1.2}}}

>> SplitBy(Tuples({1, 2}, 3), First)
{{{1,1,1},{1,1,2},{1,2,1},{1,2,2}},{{2,1,1},{2,1,2},{2,2,1},{2,2,2}}}
