How can i create a image array includes files from a specific folder?

how can i create a database from images in a folder? here is my code but it is giving error.

directory = fullfile('./buildings');
images = dir(fullfile(directory,'*.jpg'));
names = {images.name}';

I=zeros(numel(names),144,176,3); %size of the images are constant and 144*176*3

for k=1: numel(names)

      I{k} = imread(fullfile(directory,names{k}));
      I{k}=tempI;
      figure; imshow(I{k});
      %operations
  end

Error is this:

Cell contents assignment to a non-cell array object.

Error in application2exercise3 (line 9)
    I{k} = imread(fullfile(directory,names{k}));

What is tempI? It's not defined.

ignore the

I{k}=tempI;

line it is comment outed normally.

Try it like this:

images = dir(fullfile(directory,'*.jpg'));
names = {images.name}';

I=cell(numel(names), 1);
for k=1: numel(names)
  I{k} = imread(fullfile(directory,names{k}));
  imshow(I{k});
end

The problem was that you first defined I as a 3D numerical array and then was trying to stuff 3D color images into it as if I were a cell, but I was not a cell array.
