Hi,
I'm trying to see if a specific value exists for more than 2 seconds.
here is my code:
isOK2 = (Discard2_to_end <=Discard2value); % logical array
t = 2*fsamp; % 2 seconds interval
I want to use if statement if 1 exists for more than 2 seconds.
Any help would be appreciated. Thanks in advance.

isOK2 = reshape(isOK2, 1, []); %need row vector
starts = strfind([0, isOK2], [0 1]);
stops = strfind([isOK2, 0], [1 0]);
burst_duration = stops - starts + 1;
burst_is_long_enough = burst_duration >= t;
starts = starts(burst_is_long_enough);
stops = stops(burst_is_long_enough);
starts and stops will now be vectors of starting and ending indices of places with bursts that were long enough. They will be empty if there were no sufficiently long bursts.
