For loop with nested if loop

code is shown below:

drop_time =[];
for i = 1:height(HipVel)
    if all(HipVel(i,1) > .0014)&all(KneeAngle < minAngle)
    counter = [VJ_P1_T1.data(i,1)];
    drop_time(:,1)= [counter]; 
    end
end 
disp(drop_time)

The drop time matrix is empty after running this loop. I want it to show the time in the data when hip velocity is above a certain value and the knee anlge is below a certain value.

Thanks!

I want it to show the time in the data when hip velocity is above a certain value and the knee anlge is below a certain value.

If the result is empty, it likely means this condition is never satisfied in your data.

Perhaps this is what you want,

condition=( (HipVel > .0014)  & (KneeAngle < minAngle);

drop_time = VJ_P1_T1.data( condition )

or

drop_time = VJ_P1_T1.data( find(condition,1) )
