No error no output while I run the code

%%Diffractive axicon%%

%Clear all memory

% Defining Grating Parameters

N=500; %Define Matrix sizes

A=ones(N,N); %Define Matrices by assigning 1 to all pixels r=ones(N,N);

P=50;%Define the period of the grating

FFr=0.5;%Define fill factor for radial periodicity

% Constructing the grating

x=1:N;

y=1:N;

del=5;

[X,Y]=meshgrid(x*del,y*del);

r=sqrt((X-N/2*del).*(X-N/2*del)+(Y-N/2*del).*(Y-N/ 2*del));

A(rem(r,P)<P/2)=exp(1i*pi);

A(r>N/2-2)=0;

%Observing the grating output in the far-field

%See appendix for function definition

%norm_output p(A,N)

No error no output while i run the code

Does anyone have any advice? Any form of assistance will be appreciated. Thank you.

What do you expect as "output" ?

If you remove the ; behind the lines, you can see the values of the variables that are computed therein.

design of a diffractive axicon.

I don't see a variable design_of_a_diffractive_axicon that you could output.
