RDMIMIC2WAVE does not work in Octave

[GoogleCodeExporter]

RDMIMIC2WAVE does not work in Octave:

[tm,signal,Fs,recList,sigInfo]=rdmimic2wave(32805,'2986-12-15-10-00',[],0,2);

Give an empty signal and tm variables. 
This is related to the expression on the RDMIMIC2WAVE code:

matched_id=regexp(matched,'(\<s\d\d\d\d\d)');

We will need to be modified to work with Octave's regular expression function 
and syntax.
