Find empty line in text file and build array

Hello everyone, I need help with this, please. If I have a text file (.txt) which contains the following:

1 1
1 1

2 2
2 2

3 3
3 3

I want to read this file and save the data into an array the saves the data in a new dimension everytime it finds an empty line. What I mean is that I would like to save all the data into 'array' such that:

array(1,:) = [1 1;1 1]

array(2,:) = [2 2;2 2]

array(3,:) = [3 3;3 3]

Thank you for your time!

if isunix()
   %fake data
   S = sprintf('1 1\n1 1\n\n2 2\n2 2\n\n3 3\n3 3\n')
else
    S = fileread('YourFile.txt');
end

S = 
    '1 1
     1 1
     
     2 2
     2 2
     
     3 3
     3 3
     '

blocks = regexp(S, '\r?\n\r?\n', 'split')

blocks = 1×3 cell array
    {'1 1↵1 1'}    {'2 2↵2 2'}    {'3 3↵3 3↵'}

block_values = cellfun(@(s) cell2mat(textscan(s, '')), blocks, 'uniform', 0)

block_values = 1×3 cell array
    {2×2 double}    {2×2 double}    {2×2 double}

array = cat(3, block_values{:})

array = 
array(:,:,1) =

     1     1
     1     1


array(:,:,2) =

     2     2
     2     2


array(:,:,3) =

     3     3
     3     3
