Hi,

I want advice on how to make this code more efficient.

We have2 groups S and T. For each I want to attribute the aS or aT variables position that correspond to the respective input (searching in subS and subT, respectively).

Can you help?

Thanks!

input = '003'
% S group
subS = {'001','002','003',...};
aS = {'R','O','O',...};
% T group
subT = {'01','02','03'...};
aT = {'O','O','R',...};
if % S group
        if  strcmp(input,subS(1))
            a = aS(1)
        elseif strcmp(input,subS(2))
            a = aS(3)
        elseif strcmp(input,subS(2))
            a = aS(3)
        else
            ...
        end       
else % T group
        if  strcmp(input,subT(1))
            a = aT(1)
        elseif strcmp(input,subT(2))
            a = aT(3)
        elseif strcmp(input,subT(2))
            a = aT(3)
        else
            ...
        end
end
