fvec_median method
returns the median of a vector
The QuickSelect routine is based on the algorithm described in "Numerical recipes in C", Second Edition, Cambridge University Press, 1992, Section 8.5, ISBN 0-521-43108-5
This implementation of the QuickSelect routine is based on Nicolas Devillard's implementation, available at http://ndevilla.free.fr/median/median/ and in the Public Domain.
\param v vector to get median from
\return the median of v
Implementation
double fvec_median(
ffi.Pointer<fvec_t> v,
) {
return _fvec_median(
v,
);
