Interface to MatLab

MatLab is an extremely powerful software package that is very useful for post- and preprocessing as well as analysing the computed data in detail. Therefore we include two MatLab-scripts in the NaSt3DGP -package. These scripts, ReadNaSt3D.m and WriteNaSt3D.m, can be used within Matlab to read or write data in the format that navsetup produces when using the -g switch. The format of these files is shown in table .

Table: file format generated by navsetup -g

type	count	description
int	3	Number of cells ($M,N,K$) in each direction (including ghost cells)
float	$M$	Coordinates of grid lines in $x$-direction
float	$N$	Coordinates of grid lines in $y$-direction
float	$K$	Coordinates of grid lines in $z$-direction
float	$M\cdot N\cdot K$	Data of the corresponding field

After installation of the NaSt3DGP-package, the MatLab-scripts can be found in tools/matlab.
