how to store 2 matrices generated as output of two iterations of a loop, find their difference in next step in matlab

To store the output of two iterations of a loop in MATLAB and find their difference in the next step, you can follow these steps:

1. Initialize an empty cell array to store the matrices generated in each iteration:

main.m
mat_array = cell(2,1);
23 chars
2 lines

2. Perform the loop and store the matrices generated in each iteration:

main.m
for i = 1:2
  % Generate matrix in each iteration
  mat = rand(3,3); % Replace with your own matrix generation code
  
  % Store the matrix in the cell array
  mat_array{i} = mat;
end
184 chars
8 lines

3. Access the matrices from the cell array and find their difference:

main.m
mat_1 = mat_array{1};
mat_2 = mat_array{2};

difference = mat_1 - mat_2;
73 chars
5 lines

Now, the difference variable will contain the difference of the two matrices generated in the last two iterations of the loop.

Note: Make sure to replace the rand(3,3) function with your own matrix generation code according to your requirements.
