+ | For illustrating how that works, let consider a domain length $L$ (in an arbitrary direction) split in $2$ parts with lengths $L_1$ and $L_2$, respectively (see the figure below). Discrete coordinates are distributed with a given law (by considering here $N_1=6$ for the first segment, $N_2=8$ for the second one). \\ The origin coordinate is not included in the procedure. It is added by the code.\\ The coordinate located at the upper end of the segment belongs to this segment, not to the following one. | ||
