How to make a tif stack into a meshgrid?

I have tif files that have 5 z slices in them. I would like to create a meshgrid from these image slices. All x and y should be the same coordinates. Only the z should be changing. I am unsure how to go about this. I am unsure how to make a meshgrid from images instead of data values. Any help would be great. Thanks!

Review the documentation for imread:
Specifically, the example with 'corn.tif' will show you different techiques for reading the seperate channels. A possible way to get what you want could be:
x = 1068;
y = 256;
z = 5;
stack = zeros(x,y,z);
for zz = 1:z
stack(:,:,zz) = imread('yourtif.tif', zz);

It would sometimes be nice if imread() supported vectors of indices or 'all' for reading from TIFF files, like it does for GIF files. But I guess for GIF files the images are certain to be the same size, which is not the case for TIFF files.
