◆ Pad() [1/2]

static std::vector<double> OpenSim::Signal::Pad ( int  aPad,
int  aN,
const double  aSignal[] 
)
static

Pad a signal with a specified number of data points.

The signal is prepended and appended with a reflected and negated portion of the signal of the appropriate size so as to preserve the value and slope of the signal.

Parameters
aPadSize of the pad– number of points to prepend and append.
aNNumber of data points in the signal.
aSignalSignal to be padded.
Returns
Padded signal. The size is aN + 2*aPad.

◆ Pad() [2/2]

static void OpenSim::Signal::Pad ( int  aPad,
OpenSim::Array< double > &  aSignal 
)
static

◆ ReduceNumberOfPoints()

static int OpenSim::Signal::ReduceNumberOfPoints ( double  aDistance,
Array< double > &  rTime,
