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

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');

Unable to perform assignment
because the left and right sides
have a different number of
elements.
