Index in position 2 exceeds array bounds (must not exceed 1). Error in S=stepinfo​(ScopeData​(1:size(Sc​opeData,1)​,2)

hi! i just wrote the optimization code for fuzzy membership using firefly algorithm. I use this code:

%clear
clc
%inisialisasi firefly
alpha = 0.01;
beta = 0.2;
jff = 30;
iter = 0;
maxiter = 50;
errorr = 100000;
errmin = 0.001;
% posisi awal firefly
batas = [-500 -380; %E
 -300 -250;
 -450 -300;
 -300 -180;
 -50 0;
 -220 -150;
 -10 5;
 -15050 -14950; %dE
 -1000 -950;
 -4950 -4850;
 -5 5;
 4900 4990;
 500 600;
 14950 15050];

for i=1:jff
 for j=1:size(batas,1)
 ff(i,j)=(rand*(batas(j,2)-batas(j,1)))+batas(j,1);
 end
end
while errorr>errmin && iter<maxiter
 iter=iter+1;
 for i=1:jff
 
sim mppt_buck;

S=stepinfo(ScopeData(1:size(ScopeData,1),2),ScopeData(1:size(ScopeData,1),1));
bright(i,1) = mean(ScopeData(round(S.SettlingTime*1000):size(ScopeData,1),2));
bright(i,2) = S.SettlingTime;
bt(i,1) = (200-mean(ScopeData(round(S.SettlingTime*1000):size(ScopeData,1),2)))/10+S.SettlingTime;
bright;
 end
 ffl=ff;
 for i=1:jff
 for j=1:jff
 for k=1:size(batas,1)
 if bt(j,1) < bt(i,1)
 ff(i,k)=ff(i,k)+(beta*(ff(j,k)-ff(i,k)))+((maxiter-iter)/maxiter)*alpha*(rand-0.5);
 if ff(i,k)<=batas(k,1)
 ff(i,k) = batas(k,1);
 end
 if ff(i,k)>=batas(k,2)
 ff(i,k) = batas(k,2);
 end
 
 end
 end
 end
 end
 for i=1:jff
 if bt(i,1) == min(bt)
 kecil = i;
 end
 end
 errorr = max(max(abs(ffl-ff)));
 clear bright bt duty input eml fis2 ruleList out dduty
end
ff(kecil,:)

but in command window i just had an error like this

> In fireflybismillah (line 36)

Index in position 2 exceeds array bounds (must not exceed

1).

Error in fireflybismillah (line 42)

S=stepinfo(ScopeData(1:size(ScopeData,1),2),ScopeData(1:size(ScopeData,1),1));

It is my understanding that you are getting an error because you are trying to extract a column that is not a part of the 2-D matrix and hence, you are getting this error.
