Hi. I am a begginer.

I did a sample "Calculate high and low temperatures" with matlab analysis. I want to write data in a specified field in the new channel. I do not know how to do that. I already replace the empty spaces with channel ID and Api key. Then, when i try to set the field that i want to, it returns an error.

Is it right doing like I mention here:

thingSpeakWrite(writeChannelID,'Fields',[2],maxTempF,'timestamp',timeMaxTemp,'WriteKey',writeAPIKey);

I think you need to specify the name value pair 'values' when you use 'fields' Have a look at the examples on the doc page for thingSpeakWrite. If you get an error, it helps to provide the text of your error with the question.
