Answer 1

[Andrei Bobrov]

daily_avg_u(:,:,end + (1:2)) = zeros([size(daily_avg_u(:,:,1)),2]);

[Rik]

daily_avg_u(:,:,end + (1:2)) = 0;

works as well and might be clearer as to what is going on

Answer 2

You can use the cat function to concatenate arrays in a specific dimension:

A=rand(81,81,30);
B=rand(81,81);
%or: B=zeros(size(A,1),size(A,2),1);
C=cat(3,A,B);
