get_moment Function

public pure function get_moment(QQ, cxDir, expX, pdf) result(mom)

Calculate the moment of a centain order The moment of a distribution $f_i$ is defined as:\n $$m_{x^{p}y^{q}z^{r}} = \sum_{i}^{Q} c^{p}_{xi} c^{q}_{yi} c^{r}_{zi} f_i$$ The fucntion argument expX is array of size 3, which contains the values of \f$p, q, r\f$
