This string of code is taken from the thingSpeak documentation for matlab. I just copy and paste but still got this error. I would very much appreciate it if anyone can tell me where i did wrong

Dion - which version of MATLAB are you using? If you type doc thingSpeakWrite what does the documentation say about the data (second) input (are strings allowed)?

When you write string data to ThingSpeak, it generally wants to have a cell array. You should not usually need to do the String() conversion yourself. Try
thingSpeakWrite(349672,{ans},'Location',[-40,23],'WriteKey',writeKey);
and
thingSpeakWrite(channelID,{2.3,'on','good'},'Location',[-40,23],'WriteKey',writeKey);
Ill have a look at fixing that documented example, thanks for pointing it out.
