% Use parallel computing to calculate the average of the matrix
parfor i = 1:size(A, 1)
     mean_row(i) = mean(A(i, :));
end

% Display results
disp(mean_row);

**Code Logic Analysis:**

* `rand(1000, 1000)` creates a matrix with 1000 rows and 1000 columns of random numbers.
* The `parfor` loop calculates the average of each row in parallel.
* `mean(A(i, :))` calculates the average of the `i`-th row.
* `disp(mean_row)` displays the results.

**Parameter Explanation:**

* `A`: The i
