transformToSpatialDomainFromDFTGrid

transform from \((k,l,z)\) on the DFT grid to \((x,y,z)\)

---

Declaration

 u = transformToSpatialDomainFromDFTGrid(u_bar)  

Parameters

• u_bar a complex-valued matrix of size [Nk_dft Nl_dft Nz]

Returns

• u a real-valued matrix of size [Nx Ny Nz]

Discussion

Performs an inverse Fourier transform to take a matrix from the DFT grid back to the spatial domain.
