how to display a montage of images from a dataset

Hello I am using the AT&T standard database for face recognition. I want to display a montage of just a particular face of one individual in the screen for all the 40 individuals in the database.

This is my initial code

 %extract the face databse from the folders

 facedatabase=imageSet('orl_faces','recursive');

 %display montage for the first image

 montage(facedatabase(1).ImageLocation);

 %createa a gallery of all individuals

 for i=0:size((facedatabase),2)
    imagegallery{i}=read(facedatabase(i),1);
 end
 montage(imagegallery(1).ImageLocation);

 %

In the second part of the code where I want to show a gallery of all the individuals as a montage in one image its showing the follwing error

 Subscript indices must either be real positive integers or logicals.
Error in face_databse_extraction (line 11)
    imagegallery{i}=read(facedatabase(i));

Kindly tell me how to resolve this error

You start your i loop from 0, and try to index at i. It is not permitted to index at 0 in MATLAB. Your loop should start at 1.
