==================

**Ratings:**


* nb_rela: number of relationships stored in the sd_liste_rela.


* nb_coef_1rel: number of coefficients in a linear relationship ("left" part of the equation). The coefficients can be: real or complex.


* nb_coef_tot: total number of coefficients of the set of linear relationships stored in the sd_liste_rela. nb_coef_tot = nb_coef_1rel (1) +nb_coef_1rel (1) +nb_coef_1rel (2) +...


* coef_impo: value imposed for the linear relationship ("right" part of the equation or "second member"). The imposed value can be: real, complex, or function.

    RLTC (1): type of coefficients for relationships' REEL 'or' COMP '.




Subject". RLTV"
-------------

This object has a length of 1.

RLTV (1): type of the second members of the relationships' REEL ',' ',' COMP 'or' FONC '.




Subject". RLNT"
-------------

This object is of length nb_rela.

It contains the number of coefficients for each relationship.


.. code-block:: text

    RLNT (irela): number of coefficients of the irela relationship = nb_coef_1rel (irela).




Subject". RLPO"
-------------

This object is of length nb_rela.

It allows you to "point" (for a given relationship) into objects. RLCO,. RLNO and. RLDD.

These 3 objects have the same dimension and are pointed at the same way.


.. code-block:: text

    RLPO (irela): address in. RLCO (for example) of the last coefficient of the irela relationship.


    RLCO (RLPO (irela) - RLNT (irela) + 1) is the 1st term in the irela relationship.




Subject". RLCO"
-------------

This object is of length nb_coef_tot.

It contains the coefficients (R or C) of the equations.




Subject". RLNO"
-------------

This object is of length nb_coef_tot.

It contains the names of the nodes involved in the relationships.




Subject". RLDD"
-------------

This object is of length nb_coef_tot.

It contains the names of the CMPS involved in relationships.




Subject". RLBE"
-------------

This object is of length nb_rela.

It contains the second members of relationships.

RLBE (irela): second member of the relationship irela = coef_impo (irela).




Subject". RLSU"
-------------

This object is of length nb_rela. It is an indicator of whether linear relationships should be taken into account (or not).

In fact, before "pouring" the linear relationships into the sd_charge, we examine whether certain relationships are not given in several copies (duplicates).


.. code-block:: text

    RLSU (irela):

    /0 -> the irela relationship must be taken into account.

    /1 -> the irela relationship is a duplicate of a previous relationship.

    It should not be taken into account.
