How to create database to store values

I have extracted two eatures of an image and have saved it in a variable

A=[f1 f2]%f1,f2 features

now i have 100 images and i want to save it to database,so finally my database will contain values of size 100x2

please help

Answer 1

for i = 1 : 100  % 100 is number of images
   A{i} = [f1 f2]; % make A as a cell
end

save('features.mat','A');   % create database

i have used 2 uiget file to select different images say fingerfrint and iris,extracted features and saved them a=[f1 f2];

now if i select other finger and iris image the features must be added in same database

Yes like that only it will work. Put that inside the for loop.

for i=1:100

if i dont know how many files am choosing ,what must be done

for i = 1 : 2
     [file path] = uigetfile('*.jpg','Select the image');
     I = imread(strcat(path,file));
     % Extract the feautures
     % f1 f2 are generated
     A{i} = [f1 f2];
end

save('features.mat','A');

for 100 images, It is not possible to select all the 100 images manually, So

srcFiles = dir('E:\New Folder\*.jpg') % the folder in which ur images exists
for i = 1 : length(srcFiles)
    filename = imread(['E:\New Folder\',srcFiles(i).name]);
    inImage = imread(filename);
    % Generate the features f1 and f2
    Feature{i} = [f1 f2];
end
save('featuresextract.mat','Feature');

I am using 2 uigetfile

one for face f1 and other for iris f2

A=[f1 f2],

if am choosing more images,how to append it to the database

See the above comment. I answered for that also
