I have a data in which the first column gives the time and the second column gives the velocity. The time varies from 0 to 0.8 seconds.I want to divide the time into groups starting from 0 to 0.1 s, 0.1 to 0.2 ..., 0.7 to 0.8 s.Then take the count of the velocity in the respective group.

Then take the count of the velocity in the respective group What does that mean?

TIMES = DATA(:,1) ;
VELS = DATA(:,2) ;
TakeTheCountOfTheVelocityFunction = @(V) numel(V) ; % or whatever you mean by this?
[n, GroupIDX] = histc(TIMES,0:0.1:0.8) ; % GroupIDX specifies the group
Result = accummarray(GroupIDX(:), VEL(:), TakeTheCountOfTheVelocityFunction)
