MATLAB: Problem with imshow command

Question

I am trying to display multiple images in one figure using the following code:

[imgs labels] = readMNIST('t10k-images-idx3-ubyte', 't10k-labels-idx1-ubyte', 50, 10);
for i=2:50
im=imgs(:,:,i);
im=255.*im;
name = ['image',num2str(i),'.jpeg'];
imwrite (im,['image',num2str(i),'.jpeg']);
end
imshow(im);

But the code gives this error:

Error using fopen
First input must be a file name of type char, or a file identifier of type double.
Error in imshow (line 25)
    fid = fopen(imgFile, 'r', 'b');
Error in test (line 24)
imshow(BW2,'notruesize')

if I remove the imshow (im); command, the code works fine and save the image files without any problem. I am using Matlab 2014b. Thanks in advance.

Thanks for the answers. But it was may be some corrupted files problem. I have re-installed matlab and everything is working fine now.
