You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: StationaryDist_Case2.m
    path of file: ./repos/VFIToolkit-matlab/StationaryDist
    
    the code of the file until where you have to start completion: function StationaryDist=StationaryDist_Case2(Policy,Phi_aprimeKron,Case2_Type,n_d,n_a,n_z,pi_z,simoptions)
%Note: N_d is not actually needed, it is included to make it more like Case1 code.

N_d=prod(n_d);
N_a=prod(n_a);
N_z=prod(n_z);

N_d=prod(n_d);
N_a=prod(n_a);
N_z=prod(n_z);

if exist('simoptions','var')==0
    simoptions.seedpoint=[ceil(N_a/2),ceil(N_z/2)];

    simoptions.verbose=0;
    simoptions.maxit=5*10^4; %In my experience, after a simulation, if you need more that 5*10^4 iterations to reach the steady-state it is because something has gone wrong
