Got Kinect/Projector Calibration Matrix, now need to use it on GPU

I have been using ofxKinectProjectorToolkit to get the calibration matrix in the form:

-0.0105471 0.0023608 -0.00750171 2.69871 0.000712 0.0195164 -0.00822051 0.785891 0.000318565 0.00364232 -0.0139585 I am not entirely sure what it is, looks like view matrix though. The question for me is how to use it on GPU? Are there examples?
