How can I find if there is at least one particular element in the string?

Hello,

s =(1111,1112,1121,1211,2111,2112,2121,2211,2122,2112,2212,2212,2222,1122,1221,1222)

I want to know if there is any way to know which of the elemnts contains only one '1'?

You can convert it to a string and then find how many contains a single 1

x = [1111,1112,1121,1211,2111,2112,2121,2211,2122,2112,2212,2212,2222,1122,1221,1222];
idx = cellfun(@numel, strfind(string(x), '1'))==1;
y = x(idx);

Result

>> y
y =
        2122        2212        2212        1222
