It's easy to use the gpspipe utility to capture GPSD's reports to a file.

Sorry, I'm not familiar enough with matlab to tell you how to make that work
in any detail.  You can probably write code in it to open a TCP/IP connection
to port 2947, and I see there are JSON libraries that will help you unpack
its reports.

You probably want to read the Client HOWTO:

http://www.catb.org/gpsd/client-howto.html

If you do succed in writing matlab client code, please consider putting
it on the matlab file exchange so others can use it.  Then send us the URL
so we can include it in our list of client implementations.
