Hello Mohammed,
As far as I know, Matlab does not support reading of RINEX observation/navigation files. I created functions and classes to read RINEX and other GNSS-related files (see GNSS-toolbox). You can load RINEX to Matlab OBSRNX object as following:
addpath(genpath('path_to_GNSS-toolbox/src')); % Add path to toolbox functionality
obs = OBSRNX('your_rinex_filepath');
When the OBSRNX object is created in Matlab you can querry observations and perform slicing as you want. I do not test it under R2009a, but I guess it should work.

Hello, I have downloaded the code and was using it for testing my RINEX navigation and observation files but the function keeps giving me errors.
Can you please guide me what am I doing wrong here?
thank you and please find the attached screen shot to this comment.

str2num is not returning a scalar. Possibly the text to be converted is blank or has more than one number.
In most cases, str2double should be used if exactly one number is expected.

Thank you I will see if I can modify the code for the latest RINEX versions.

MATLAB supports reading RINEX data directly into MATLAB from R2022a onwards. Use the function rinexread. See https://mathworks.com/help/nav/ref/rinexread.html
