i cannot understand MATLAB syntax

Question

In MATLAB, i was faced with a incomprehensible syntax.

for i = [1:n-1,n+1:N]
    Z{i} = U{i}(:,r);
end

if you knows exactly, please let me know. (if you show some example(e.g. when n=1, N=3), i can understand your explain easily.)

This syntax basically means:

for i = [1:n-1,n+1:N]

This just means that i will sequentially take the values defined in the array: 1 till n-1 increasing by 1 and after it will continue from n+1 till N. It will skip n in other words.

Z{i} = U{i}(:,r);

{ represent cells so the ith cell of Z (imagine Z and U as cell arrays) will be assigned the content of ith cell of U from which it will keep though only the r-th column (I guess its a matrix of some kind).
