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: mini_max_row_simplex.m
    path of file: ./repos/SGDLibrary/problem
    
    the code of the file until where you have to start completion: classdef mini_max_row_simplex
%function [Problem] = mini_
    
function [Problem] = mini_max_row_simplex(A)
%
% Inputs:
%       A           matrix of size dxn.
% Output:
%       Problem     problem instance. 
%
%
% The problem of interest is defined as
%
%           min f(w) = max a_i^T x : x in probability simplex
%           where a_1^T, a_2^T, ..., a_n^T are the rows of A
%
% "w" is the model parameter of size d vector.
