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.
Invalid use of operator "

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)

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.
