This is a sample data for 3. I am stuck at how to write the same logic for 10 such that there should be comparision for all the input values given for T1 ,T2, .... T10.

I = zeros(1,3);
if T1 == T2
    I(1,1)= 1;
    I(1,1)= 0;
elseif T1 > T2
    I(1,1)= 1;
    I(1,2)= 0;
elseif T1 < T2
    I(1,1)= 0;
    I(1,2)= 1;
end

note: only one element in I should be equal to 1 in the end in such a way that the highest T gets the value 1 in I.

在 MATLAB Online 中打开

Assuming T1, ..., T10 are scalars,

T = [T1 T2 T3 T4 T5 T6 T7 T8 T9 T10];
[~,idx] = max(T);
I = zeros(size(T));
I(idx) = 1;

Can you dynamically create and operate on variables with numbered names like T1, T2, T3, etc.? Yes.

Should you do this? The general consensus is no. That Answers post explains why this is generally discouraged and offers several alternative approaches.
