Getting Kinect sensor data from matlab

I have kinect for PC and the new microsoft kinect SDK (not the beta). I was able to connect to the kinect from Matlab (using net.addassembly(<microsoft.kinect.dll>), and register an event listener (e.g., to DepthFrameReady event using addlistener). My event handler get called indeed (30 times a sec), but, when I copy the image data in the event handler to a matlab int8 array (using, DepthFrame.CopyPixelDataTo(frameBits)), the resulting matlab array, frameBits, is all zeros.
Any help on how to get the data from kinect sensor using microsft sdk would be highly appriciated.

Hi, i have a problem with kinect v1 and matlab 2013, I need to acquire data from the joints when a person is walking but I get very few data because is very slow the sample of the "getdata" to get all the jointscoordinates each second, and thats give me only some angles and looses others that I need. This is the code. I hope someone could help me :(
depthVid = videoinput('kinect',2,'Depth_640x480');
preview(colorVid);
preview(depthVid );
triggerconfig(depthVid,'manual');
depthVid.FramesPerTrigger=1;
depthVid.TriggerRepeat=inf;
set(getselectedsource(depthVid),'TrackingMode','Skeleton')
start(depthVid);
himg = figure;
while ishandle(himg);
trigger(depthVid);
[depthMap, ~, depthMetaData]= getdata(depthVid);
if sum(depthMetaData.IsSkeletonTracked)>0
cont=cont+1;
skeletonJoints= depthMetaData.JointImageIndices(:,:,depthMetaData.IsSkeletonTracked);
jointCoordinates=depthMetaData.JointWorldCoordinates(:,:,depthMetaData.IsSkeletonTracked);
imshow (depthMap, [0 4096]);
hold on;
graficar_esqueleto(skeletonJoints)
hold off;
i=i+1;
%Angulos de articulación de rodillas
jointCoordinates
%der
ang1=Angulo(13,15,jointCoordinates);
ang_rodilla1(i)=(180-ang1)
%izq
ang2=Angulo(17,19,jointCoordinates);
ang_rodilla2(i)=(180-ang2)
else
imshow (depthMap, [0 4096]);
end
drawnow
end
stop(depthVid);
clear depthVid;
