List of all members.

## Public Member Functions
| emix (const RV &rv)
| Default constructor.
void | set_parameters (const vec &w, const Array< epdf * > &Coms, bool copy=true)
| Set weights `w` and components `Coms` , Coms are not copied!
vec | sample () const
| Returns a sample, from density .
vec | mean () const
| return expected value
double | evalpdflog (const vec &val) const
| Compute log-probability of argument `val`.
vec & | _w ()
| returns a pointer to the internal mean value. Use with Care!
void | ownComs ()
| Auxiliary function for taking ownership of the Coms().
virtual mat | sampleN (int N) const
| Returns N samples from density .
virtual double | eval (const vec &val) const
| Compute probability of argument `val`.
virtual vec | evalpdflog_m (const mat &Val) const
| Compute log-probability of multiple values argument `val`.
mpdf * | condition (const RV &rv)
| Return conditional density on the given RV, the remaining rvs will be in conditioning.
epdf * | marginal (const RV &rv)
| Return marginal density on the given RV, the remainig rvs are intergrated out.
const RV & | _rv () const
| access function, possibly dangerous!
void | _renewrv (const RV &in_rv)
| modifier function - useful when copying epdfs
## Protected Attributes
vec | w
| weights of the components
Array< epdf * > | Coms
| Component (epdfs).
bool | destroyComs
| Flag if owning Coms.
RV | rv
| Identified of the random variable.

## Detailed Description
