create a grid fuction

I wanna write a function .mfile to create a computational grid.

    function kgrid =  test_environment 
Nx = 10;           
Ny = 10;            
Nz = 10;            
dx = 0.001;        
dy = 0.001;        
dz = 0.001;        
kgrid =  test_environment (Nx, dx, Ny, dy, Nz, dz);

why do i get this error: Too many input arguments.????

It is because in your function declaration, you do not define inputs.

 function kgrid = test_environment(nx,dx,ny,dy,nz,dz)

Lets you input those parameters.

Look at the help on varargin and nargin if you want optional arguments.

But if i use that i ge this error :

Maximum recursion limit of 500 reached. Use set(0,'RecursionLimit',N) to change the limit. Be aware that exceeding your available stack space can crash MATLAB and/or your computer.

And if use set(0,'RecursionLimit',7000) matlab crash :(

I know i call this function repeatedly, but how can i change the function to call it only one more time????

I'm using this example but

http://www.k-wave.org/documentation/example_ivp_3D_simulation.php#heading3

but i dont have any idea to create a function. I mean i dont know what should be my inputs and outputs, and how these functions are nested to eacht other.

Can u guys help mepls??
