Threshold detector

It takes parts of incoming vector that above threshold and return cell array of parts.

It takes incoming vector then find all parts that above threshold and cut the vector to above threshold parts.

It returns cell array of above threshold parts of the vector and two arrays of start-indexes and end-indexes.

[ parts, starts, ends ] = ThresholdDetection( Vector, threshold )
%% find start and end points
a=Vector>=threshold;
a=a(:);
a=[0;a;0];
a=diff(a);
starts=find(a==1);
ends=find(a==-1)-1;
%% cutting
parts=cell(length(ends),1);
for i=1:length(ends)
parts{i}=Vector(starts(i):ends(i));
end
end
