Hi, QGIS core (the analysis library) do not expose such function directly, but it does have methods to compute derivatives that are internally used by all the "9 cells" algorithms (slope, aspect, ruggedness and hillshade) and the derivative calculation is accelerated by OpenCL if available, exposing the derivatives directly requires a small development but it is definitely possible.
