I don't quite understand what the following code is doing.
numFolder=fullfile('NumberZero/','Zero/');
for i=1:10;
numName=sprintf('%d.bmp',i);
image1=imread([numFolder, numName]);
im1(:,:,i)=image1; % what is this line doing?
end

im1(:,:,i)
means take all elements of your 3d array in the first and 2nd dimensions and only the i'th value in the 3rd dimension.
So basically it turns your data from 3d to 2d in this case by extracting just one slice from the 3rd dimension of a volume.
doc colon
The comma is just the standard syntax for separating the dimensions of your matrix which is why in your case I could easily see that im1 is 3d.

I'm not really familiar with neural networks so I'm not sure I would be able to help with that.
