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: example_Dirty_Classify.m
    path of file: ./repos/MALSAR/examples
    
    the code of the file until where you have to start completion: 
%%
%nested cross validation for testing the logistic dirty model
%The stratified cv are integrated into method to handle
%"not_enough_data_sample" problems and privide more accur

addpath('../MALSAR/c_files/prf_lbm/'); % load projection c libraries. 
addpath('../MALSAR/utils/'); % load utilities
addpath('./train_and_test/'); 


% simulate the data
n = 50;
d = 300;
T = 10;

X = cell(T, 1);
Y = cell(T, 1);
W = randn(d, T);
W_mask = abs(randn(d, T))<1;
W(W_mask) = 0;
for i = 1: T
    X{i} = randn(n, d);
    Y{i} = sign(X{i} * W(:, i) + rand(n, 1) * 0.01);
