MATLAB: Could anyone explain the code for me

explain code

file_path = dir(''); fid = fopen(''); pattern_col = 0;
while ~feof(fid)
    pattern_col = pattern_col + 1;  %coloum increment is 1
    exp = [];               %initialize the sample data
    area_sample = [];
    angle_sample = [];
    fcontent = fgetl(fid);  %get pattern size
    pattern_size = fcontent;
    fcontent = fgetl(fid);  %get time interval
    pattern_hour = fcontent;
    fcontent = fgetl(fid);  %get file path
    file_path_disp = fcontent;
    file_path = dir(fcontent);      %should be specific
    file_num = size(file_path, 1);
Could anyone explain the code for me ? It can read a image file ? especially the beginning. file_path = dir(''); fid = fopen('');
Can you make up some example for me ? thanks
