bdm::RV Class Reference
#include <libBM.h>
Detailed Description
Class representing variables, most often random variables.The purpose of this class is to decribe a vector of data. Such description is used for connecting various vectors between each other, see class datalink.
The class is implemented using global variables to assure uniqueness of description:
In is a vector

Member Function Documentation
| ivec bdm::RV::findself | ( | const RV & | rv2 | ) | const |
| bool bdm::RV::add | ( | const RV & | rv2 | ) |
Add (concat) another variable to the current one,.
- Returns:
- true if all rv2 were added, false if rv2 is in conflict

| ivec bdm::RV::dataind | ( | const RV & | crv | ) | const |
when this rv is a part of bigger rv, this function returns indeces of self in the data vector of the bigger crv. Then, data can be copied via: data_of_this = cdata(ind);

| ivec & | selfi, | |||
| ivec & | rv2i | |||
| ) | const |
generate mutual indeces when copying data betwenn self and crv. Data are copied via: data_of_this(selfi) = data_of_rv2(rv2i)
