Wagner-Within-Algorithm with arg

Hello everybody, I m new to matlab. I have to use matlab for my master-thesis and I was trying to understand the code for the wagner-within problem. I will copy the code below. What is the meaning of arg_J?

Can you please also explain what is mean by Partial politics (1 x N)?

About any help I would be extremely thankful

% J           Partial politics (1 x N)
% arg_J       Arguments of the partial politics (1 x N) 

function [z , x , J , arg_J , C] = wargner_whitin(d , K , c , h);

%
% Wagner-Whitin Algorithm  
%
% Build production plans versus time cycles k =1,...,N responding production queries dk 
% and miniming the sum of following production costs  
% 
%   i) Fix production cost K_k 
%  ii) Unitary production cost c_k
% iii) Stockage unitary cost h_k
%
% Assumption : initial and final stocks are null.
%
%
% Inputs
% ------
%
% d            Queries of production througth time cycles (1 x N)
% K            Fix production cost (1 x N) 
% c            Unitary production cost (1 x N)
% h            Stockage unitary cost (1 x N)
%
%
% Outputs
% ------
%
%
% z           Optimal cost at the end of the N cycles
% x           Quantities to product (1 x N)
% J           Partial politics (1 x N)
% arg_J       Arguments of the partial politics (1 x N) 
% C           Cost transition matrix (N x N)

This is not complete code. All statements use this '%' symbol are comments on the code (Not considered during execution).

[Martin Polz]

yes. but can you explain what is the meaning of arg_J? And what does partial politics mean?

[John D'Errico]

Nobody can explain the meaning of an argument where no code is actually provided. All that is shown are comments.

Contact the source of the code and ask them.
