## Public Member Functions
virtual vec | samplecond (vec &cond, double &ll)
| Returns the required moment of the epdf.
virtual void | condition (const vec &cond)
| Update `ep` so that it represents this mpdf conditioned on `rvc` = cond.
virtual double | evalcond (const vec &dt, const vec &cond)
| Shortcut for conditioning and evaluation of the internal epdf. In some cases, this operation can be implemented efficiently.
virtual | ~mpdf ()
| Destructor for future use;.

## Member Function Documentation

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

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.
