Hi, I am using this part of code to input multiple images.
myFolder = 'Folderlocation';
% Check to make sure that folder actually exists. Warn user if it doesn't.
if ~isfolder(myFolder)
errorMessage = sprintf('Error: The following folder does not exist:\n%s\nPlease specify a new folder.', myFolder);
uiwait(warndlg(errorMessage));
myFolder = uigetdir(); % Ask for a new one.
if myFolder == 0
% User clicked Cancel
return;
end
end
% Get a list of all files in the folder with the desired file name pattern.
filePattern = fullfile(myFolder, '*.bmp'); % Change to whatever pattern you need.
theFiles = dir(filePattern);
for k = 1 : length(theFiles)
baseFileName = theFiles(k).name;
fullFileName = fullfile(theFiles(k).folder, baseFileName);
fprintf(1, 'Now reading %s\n', fullFileName);
% Now do whatever you want with this file name,
% such as reading it in as an image array with imread()
imageArray = imread(fullFileName);
Now, I want to store these images in an array, something like image(k). But any effort to it shows error. How do I do it?

The simplest solution is to just store the image data in the same structure that DIR returns:
S = dir(fullfile(myFolder,'*.bmp'));
for k = 1:numel(S)
F = fullfile(S(k).folder,S(k).name);
fprintf(1, 'Now reading %s\n', F); % optional
S(k).data = imread(F);
end
For example, the second file:
S(2).name % filename
S(2).data % image data

You can use cell array so that each cell stores an image (of different size).
im{k} = imageArray;
