Member Function Documentation

virtual const char* GrFFT_vCC::name (   )  [inline, virtual]

default name for a module (override with actual name) Reimplemented from VrSigProc.

int GrFFT_vCC::work (  VrSampleRange  output, void *  o[], VrSampleRange  inputs[], void *  i[] )  [virtual]

Generate up to output.size output points at o[output#][sample#] using data at the inputptrs[input#][sample#]. Pointers start at corresponding VrSampleIndex in the range params. output.size is a multiple of outputSize. Returns the number of outputs (<= output.size) that it was able to compute with the given input ranges. If this value is < output.size, forecast() will need to be called again. Implements VrSigProc.
