How to save multiple 2D arrays in a third dimension in simulink?

I will be reading multiple 2D arrays of the same size (100, 8) in time. The idea is to concatenate all of them in a 3D array.

How can implement this in simulink?

I'm not familiar with simulink, but in Matlab:

my3Darray = cat(3,my2Darray1,my2Darray2,<etc.>);

or, while making them:

my3Darray=zeros(100,8,10);
for ind=1:10
    my2Darray = rand(100,8); % or however you read them
    my3Darray(:,:,ind) = my2Darray;
end

Sindars code can be encapsulated in the function block in SIMULINK.

I am not sure on how to save them. I have multiple 2D arrays and I would like to save only the arrays that have a 1 in the last column.

I am receiving matrixes that have the same size but witth values non zero and zero. I would like to save into a 3D array all the 2D arrays with no zero values. Each one of them found concatenated into the 3rd dimension.

I am not sure how to implement it.

Hi,

You can accordingly place a condition for concatenating each 2D array to a 3D array. Here is a sample code(modified code of Sindar's):

N = 10; % Let Num of 2D arrays 
my3Darray=zeros(100,8,N); 
for ind=1:10 
    my2Darray = randi(50,100,8);
    my3Darray(:,:,ind) = my2Darray; 
   % check for "1" in last column and remove concatenation of 2D array if there is no  "1"
    if all(my2Darray(:,end) ~= 1) 
            my3Darray(:,:,ind) = []; 
    end 
end
