performing a command for the firts time

Hi, The question is that How should I ask matlab to perform a coomand for the first time i reach it. to make it clear I have a times(second) like this: 4 4.2 4.4 4.6 4.8 5 5.2 5.4 5.6 5.8....... and I have ti=5.1 s and I want to say that

for i=1:100 if for the first time t>=ti statements end end so the statemenst should be performed just in 5.2 and not for others.

sorry for bad spelling, this keyboard sometimes does not work well, it is Command not coomand

ti = 5.1;
for i1 = 1:numel(t)
    if t(i1) > ti
        % your statements 
        break;
    end
end

or

t = [4 4.2 4.4 4.6 4.8 5 5.2 5.4 5.6 5.8]  ;
ti = 5.1;
dt = t-ti;
ttest = abs(dt - min(abs(dt))) < eps*100;
for j1 = 1:numel(ttest)
    if ttest(j1)
        % your statements
    end
end
