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.

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
