I wanted to iterate this piece of code for 10 seconds.

disp('Opening an inlet...');
inlet = lsl_inlet(stream_result{1});
[vec,ts] = inlet.pull_sample();
start = ts;
fNIRS_record = [];
flag = 0;
while ts - start < 1 %one second data which is ~8 frames
[vec,ts] = inlet.pull_sample();
fNIRS_record = [fNIRS_record;vec];
fprintf('%.2f\t',vec);
fprintf('%.5f\n',ts);
flag = flag + 1;
end
if(flag == size(fNIRS_record,1))
%Real time channel exclusion based on threshCV
RT_HbO = fNIRS_record( :,2:2:end);%getting only HbO values at real time
%using getCV() eliminate bad channels.
RT_vertcat = mean(RT_HbO,2);%avg of all 20 channels.
RT_vertcat = array2table(RT_vertcat);
realtime_stats_HbO = groupsummary(RT_vertcat,{}, {'mean', @slope_HbO, @(v) var(v, 1), @(pk) max(pk), @(sk) skewness(sk), @(kurt) kurtosis(kurt)});
clear flag;clear RT_HbO;clear RT_vertcat;
label = trainedModel.predictFcn(realtime_stats_HbO); %<--------------It has predict and print the label and clear everything and run the loop again for desired time period which is 10 seconds.
end

tic;
while toc < 10
Timing is unlikely to be exact.

for iter = 1 : 10
tic;
... do the work
pause(1-toc);
end

It runs for one iteration and pauses for 10 seconds thats all.
See inlet = lsl_inlet(stream_result{1});
[vec,ts] = inlet.pull_sample();
start = ts;
Through inlet my data is continuos flowing in at real time.
ts is the start of frame.
I have make changes to start such that it iterates the way i want it to.
Basically i want to give it 10 seconds
while ts - start < 1 %one second data which is ~8 frames
Here it 1 second gives me 8 values and using groupsummary I am calculating statical features.
after which label = trainedModel.predictFcn(realtime_stats_HbO); using the statical feature i want run it through my model to predict a state.
Then i want to start fresh again ....till 10th second
