Given a function $f(\boldsymbol{x})$ evaluated at the quadrature points, this function calculates the derivatives $\frac{d}{dx_1}$ , $\frac{d}{dx_2}$ and $\frac{d}{dx_3}$ of the function $f(\boldsymbol{x})$ at the same quadrature points. The local distribution of the quadrature points allows an elemental evaluation of the derivative. This is done by a call to the function StdRegions::StdExpansion::PhysDeriv.

Parameters

inarray	An array of size $Q_{\mathrm{tot}}$ containing the values of the function $f(\boldsymbol{x})$ at the quadrature points $\boldsymbol{x}_i$ .
out_d0	The discrete evaluation of the derivative $\frac{d}{dx_1}$ will be stored in this array of size $Q_{\mathrm{tot}}$ .
out_d1	The discrete evaluation of the derivative $\frac{d}{dx_2}$ will be stored in this array of size $Q_{\mathrm{tot}}$ . Note that if no memory is allocated for out_d1, the derivative $\frac{d}{dx_2}$ will not be calculated.
out_d2	The discrete evaluation of the derivative $\frac{d}{dx_3}$ will be stored in this array of size $Q_{\mathrm{tot}}$ . Note that if no memory is allocated for out_d2, the derivative $\frac{d}{dx_3}$ will not be calculated.
