writeGrid

Write grid and PML properties to a k-Wave HDF5 file

Syntax

writeGrid(filename, grid_size, grid_spacing, pml_size, pml_alpha, Nt, dt, c_ref)

writeGrid creates and writes the wavenumber grids and PML variables required by the k-Wave C++ code to the HDF5 file specified by the user.

List of parameters that are written:

`filename`	name of HDF5 file to write matrix to
`grid_size`	`[Nx, Ny, Nz]`
`grid_spacing`	`[dx, dy, dz]`
`pml_size`	`[pml_x_size, pml_y_size, pml_z_size]`
`pml_alpha`	`[pml_x_alpha, pml_y_alpha, pml_z_alpha]`
`Nt`	number of time points
`dt`	time step
`c_ref`	scalar sound speed used in the k-space operator and to define the pml variables
