Convert 3D cell to 2D cell

Hey, I would like to convert the 3D cell A{x,y,z} to a 2D cell B{x,y} with row vectors of all z as elements (B{1,1} = [z(:)]). Thanks for any suggestions!

I am confused about what B{x,y} should contain: indices z or the values at all z-indices. Perhaps you can give a small(!!) example?
