Hello Berhane,
I created functions and classes to read observation and navigation RINEX files (see here https://github.com/spanikp/GNSS-toolbox). Also loading and processing of other GNSS-related files, like SP3 files or ANTEX, is supported. For example 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. Toolbox support also downloading some useful navigation data like broadcast and precise ephemeris. You can also compute satellite positions and then visualize satellite paths (there is class Skyplot which can be used for that).
Any comments, issue reports and pull requests are welcome!

read rinex showing that error
Error defining property 'satpos' of class 'OBSRNX':
Class named 'SATPOS' is undefined or does not support property validation

Hi @Mohamed Fathi could you please create an issue at https://github.com/spanikp/GNSS-toolbox/issues? If you could provide also file which you want to load that would be great.

Reading Rinex is not a supported functionality that ships with MATLAB, but there may be 3rd party tools that enable you to do it, like the one below:
