MATLAB: How to form a feature vector from text file

feature vector extract

Hi, hope anyone can help me, truly appreciated. I have 10 features inside my text file ('Dataset1_Permission.txt') and its' row by row. What I wanted is, if my AndroidManifest.txt exist this feature then output as 1, if not output as 0. So, let say I only have 1 feature inside my Dataset1_Permission.txt file, It should output like..

0010000000
text = fileread('AndroidManifest.txt'); % read input manifest file
text2 = fileread('Dataset1_Permission.txt'); % read android permission list dataset
matchStr = regexpi(text,'\"android.permission.\w*\"','match') %extract the keyword in manifest file

Best Answer

text1 = fileread('AndroidManifest.txt'); % read input manifest file
text2 = regexp(fileread('Dataset1_Permission.txt'), '\r?\n', 'split'); % read android permission list dataset
features = ~cellfun(@isempty,regexp(text1,text2));

Have you tried a loop the filename formed with sprintf?

for folder_number=1:5
    text1 = fileread(sprintf('C:\Users\ASUS\Desktop\FYP\M%d\AndroidManifest.xml',folder_number)); % read input manifest file
    text2 = regexp(fileread('Dataset1_Permission.txt'), '\r?\n', 'split'); % read android permission list dataset
    matchStr = regexp(text1,'\"android.permission.\w*\"','match'); %extract the keyword in manifest file
    features{folder_number} = ~cellfun(@isempty,regexp(text1,text2));
    disp(matchStr);
end

I don't know what you would want to do with matchStr. (Note: if you have many folders, pre-allocating the features variable may be a good idea)

By the way, I would appreciate it if you stopped doing those strcat and switched to having a variable holding the directory name, and using fullfile(). Repeating the location construction like you are is error prone. It is also not at all portable. If you were to give the code to anyone else (like us volunteers) they would first have to spend their time searching the code and editing the location information repeatedly to match their own directory names. For example I cannot just change the username ASUS in multiple places because I do not run on MS Windows.

I already showed you the code to fix this issue... More than once.
