Hi,
I wrote down this code, however, it gives me the error " Arrays have incompatible sizes for this operation. Error in Code (line 5) row = find(X==i);"
X = [12 12 12 1 1 1 1 1]
for i= unique(X)
row = find(X==i)
for j=[row]
i have some codings here
end
end
Can you please help me? Thanks,

Ran in:
Runs fine.
X = [12 12 12 1 1 1 1 1];
a=[];
for i= unique(X)
row = find(X==i);
for j=row
a=[a,5];
end
end
a
a = 1×8
5 5 5 5 5 5 5 5

Thank you very much. Yes, the problem was X which was:
X = [12; 12; 12; 1; 1; 1; 1; 1];
I did not notice that.
