I have a mat file which has 128*128*70 dimensions, which is 70 slices 128*128 images. Now, I want to display the first 10 images in these 70 images, how can I do that?

The imdisp method in the sc FEX submission allows you to display multiple images easily.
In your case, assuming that the array is called "stack", you would call it as follows:
imdisp(permute(stack, [1 2 4 3]), 'Size', [4 5]);
This will display the first 20 frames in a 4x5 grid. However, you can then use the arrow keys to scroll through the rest. The call to permute is required to get the slices stacked along the 4th dimension (the 3rd is reserved for colour).
