I have variable images of size 512x512x22, passing this variable to isosurface() shows an empty window. I have read images as

images(:,:,1) = img2bw(imread('img1.gpg'));
images(:,:,2) = img2bw(imread('img2.gpg'));  
images(:,:,3) = img2bw(imread('img3.gpg'));  
...                                          
...                                          
images(:,:,22) = img2bw(imread('img22.gpg'));
isosurface(images, 1); %This executes, but shows blank output window

What I am doing wrong here?

@MikeGarrity, I executed images = images * 2 and it works! Thanks a lot!

Ah, there's actually some interesting stuff going on in the case where your iso value is exactly equal to the values in your array. In this blog post , I talked about how that works with contour. For isosurface it's similar, but not exactly the same.
