How to write the data from a serial port into a text file using MATLAB?

Hello all. I want to write data from serial port into a text file using MATLAB. I am generating the data to serial port using Arduino software (ADC operation using Arduino). The digital data in hex format is available in serial port. But I am not able to write it to a text file using Matlab command (I can view the data both in serial monitor of arduino and hyperterminal). fwrite(s,'1'); this is the command that i used. Can anyone please help me to solve this problem? Thank you in advance.
