It says all in the summary. Nothing fancy just a convenient tool for spitting vectors.

Finally got around to trying this. I like it a lot, but I don't understand how the COL input argument works. Clearer documentation on that with examples would help.

Excellent. Thank you.

This is a great function that I am looking for.
However, it would be more perfect if
1. the array can be unsorted.
2. the indices can be returned
For example, [s,i] = SplitVec([1 2 1 3 2 1])
where
s={[1 1 1],[2,2],[3]}
i={[1 3 6],[2,5],[4]}
I do not know if it is possible

Monotonic

SplitVec(a, @(v) [0; diff(v(1:end-1)).*diff(v(2:end))<0])

OK ... I add the 'decrease' and 'increase' functions by:
case {'increase'}
fun = @(v) diff(v(:,1))<0;
case {'decrease'}
fun = @(v) diff(v(:,1))>0;

But, how to add functions for 'positive' and 'negative' values vector spliting?

Michal Kvasnicka

Will be possible to generalize this function to split vector on monotonical parts using ismonotinic function (http://www.mathworks.com/matlabcentral/fileexchange/11637-ismonotonic)?

Ingenious! Clearly explained and easy to follow. Thank you very much!

As you would expect of all of Bruno's submissions, it does exactly what it says it will do. Superb documentation.

Tom Toner

Thanks a lot for such a great function!
