Hi All,
I have a matrix
X=16x16x4000
I want to truncate it (and delete the 4000 entirely) and make it to just 16x16. How should I do this? I have tried everything from permute to using [ ] but it just doesn't work. Thanks!

You are not being specific enough to determine a unique solution. If you are happy with just the first "slice" in the 3rd dimension, then
X(:,:,1)
is a 16x16 array.
