Problem with imshow command

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.

Which imshow are you using? line 25 of the toolbox version does not appear to have an fopen.

Try which -all imshow. You might have a shadowed version.

Thanks, but no. Still giving this same error.

What did

which -all imshow

report in its output?

Also try

clear imshow

in case you just happen to have a function handle by that name around.

I don't see 'notruesize' as being one of the available input arguments. Why are you sending that in when it's not allowed?
