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.

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?
