void bdm::mpdf::from_setting

(

const Setting &

set

)

[virtual, inherited]

Load from structure with elements:

 { rv = {class="RV", names=(...),}; // RV describing meaning of random variable
   rvc= {class="RV", names=(...),}; // RV describing meaning of random variable in condition
   // elements of offsprings
 }

Reimplemented from bdm::root.

Reimplemented in bdm::mepdf, bdm::mprod, bdm::mlnorm< sq_T >, bdm::mgnorm< sq_T >, bdm::mgamma, bdm::migamma_ref, bdm::mlognorm, bdm::mlnorm< chmat >, and bdm::mlnorm< ldmat >.

vec bdm::mpdf::samplecond

(

const vec &
