If the DHT11 sensor is connected to my Arduino and I want to read the temperature and humidity data directly from that pin of Arduino to which it is attached without the help of any arduino code, is there any Matlab library available for that?

Hi! The answer would interest me as well :) When using Sadiq's modified code, I get:
Warning: Unsuccessful read: A timeout occurred before the Terminator was reached.
'serial' unable to read all requested data. For more information on possible reasons, see Serial Read Warnings.
out =
'nannannannannannannannan'
NaN
NaN
Some help would be great!

If "out" is showing Temperature: 18.00 then the implication is that the data sent by the other side is not just numeric. If you know for sure that the "Temperature:" part is always going to be there then you can use fscanf() with a format of 'Temperature: %f' to read the numeric part directly, but if there might be a variety of text then you need to analyze the text to figure out which format to use.
