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

Returns the required moment of the epdf.

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 mlnorm< sq_T >, and mgamma.
