virtual vec bdm::mpdf::samplecond	(	const vec &	cond,
		double &	ll
	)			[inline, virtual]

Returns a sample from the density conditioned on cond, .

Parameters:

	cond	is numeric value of rv
	ll	is a return value of log-likelihood of the sample.

Reimplemented in bdm::mprod.

virtual mat bdm::mpdf::samplecond_m	(	const vec &	cond,
		vec &	ll,
		int	N

Returns.

Parameters:

	N	samples from the density conditioned on cond, .
	cond	is numeric value of rv
	ll	is a return value of log-likelihood of the sample.
