My goal is to that take a folder's path as input and extract the features of every image and place it in a file to create a matrix of feature vectors of each sample , each row represent the parameters of a different sample and each column represent a different feature.

image_folder = 'C:\Users\...';
filenames = dir(fullfile(image_folder, '*.jpg'));  % read all images with specified extention, its jpg in our case
 total_images = numel(filenames);    % count total number of photos present in that folder
for n = 1:total_images
  full_name= fullfile(image_folder, filenames(n).name); 
our_images = imread(full_name); 
%%%core features extraction code.....
Vecteur=[v1,v2,v3....v116];
normalized=zscore(Vecteur)  ;
    A{n} = normalized; % make A as a cell
  end
  save('features.mat','A');   % create database
