Concatenation of three-dimensional arrays

Hello everyone,
I am trying to concatenate two three-dimensional arrays inside of a double for loop:
for i=1:length(Temperature_max)
for j=1:length(Hy1_values)
Hy1(:,j,i)=ones(length(time_first_interval),1).*Hy1_values(j); % A/m
Hy2(:,j,i)=zeros(length(time_second_interval),1); % A/m
Hy(:,j,i)=vertcat(Hy1(:,j,i),Hy2(:,j,i));
end
end
Obviously vertcat does not work. Any suggestion?

This cat call does absolutely nothing, because one array concatenated with nothing else simply returns the one array:
cat(2,[Hy1(:,j,i);Hy2(:,j,i)])
You already concatenated two arays togther (vertically) using square brackets to give one array, and then passed that one array to the totally superfluous cat call, which simply returns that same one array. Not much point in that.
Note that these are equivalent:
[A;B]
cat(1,A,B)
If you want to concatenate vertically, then you can use either.
