Member Function Documentation

template<class V , class M >

void QUESO::BetaVectorRealizer< V, M >::realization ( V &  nextValues ) const

virtual

Draws a realization.

This function draws a realization of a Beta distribution and saves it in nextValues. It internally checks whether the image set, where the realization should be drawn, belongs to the interval (0, 1] - which is the range where Beta distribution is defined over.

Implements QUESO::BaseVectorRealizer< V, M >.
