http://physionet.org/physiotools/matlab/wfdb-app-matlab/ in this link there are many 'wfdb app toolbox' . which one is usefull for sleep apnea signal extraction how do we know

[Walter Roberson]

Those are not different toolboxes: those are different version numbers. You would normally take the newest version unless you had particular reason to use an earlier one (for example needing to exactly reproduce a published work.)
