I was trying follow and replicate the example code for the Temperature/Humidity Matlab and continue to get the error as follows:
Error in /users/mss.system.Z1My17/Temperature Humidity Line:14 Column:5
In the line is the following:
13 thingSpeakWrite(writeChId, [temp, humidity, dewPointF], "Fields", [1,2,3]...
14 "TimeStamps", time, "Writekey", writeKey)

does not seem to matter whether it is a single or a double. The error is shorter if it is the double vs the single.

The ... ends the line immediately. There is no implied separator inserted. So you have a ] from the numeric list followed by the content of the second line which is some spaces and then the literal, exactly as if you had written the numeric list and then some spaces and then the string.
[1,2,3] "TimeStamps"
all as one parameter. Numeric list followed by string is not valid syntax in this context. You need to add the missing comma.

@Stephen, Thanks for the circle. I apologize as I didn't see the comma and at first I had 4 periods in there, then tried the comma at the end of the line. Tired eyes do that to me everytime.
@Walter, I just want it to run properly. It seems to run somewhat, there are still errors. The code lists numerous dew points, but then advises there is an error using Temperature Humidity line 13. Then it states to ensure the proper channel ID and Write key API are being used. From what I cans they are the proper ID and Key. Can't copy/paste into the code box. On the page I'm using there is no Code button to click on.
