intZG

Return the bottom-zero first antiderivative of a G-representation.

---

Declaration

 W = intZG(w,n=1)

Parameters

• w G-representation in [Nx Ny Nz] or [Nz N] layout
• n antiderivative order; only 1 is supported (default 1)

Returns

• W bottom-zero F-representation antiderivative in the input layout

Discussion

A G-to-F antiderivative is defined up to an additive constant. This method selects the representative that vanishes at the bottom boundary. w may use the gridded layout [Nx Ny Nz] or a vertical-first matrix [Nz N]; the returned array preserves that layout.
