I'm trying to flip a row based on its left and right maximum values and obtain an array with all these changes.

[leftMAX,left_idx]=max(leftA,[],2);
[rightMAX, right_idx]=max(rightA,[],2);
[middleMAX, middle_idx]=max(middleA,[],2);
n= size(A,1);
   for ii = 1:n-1
      if leftMAX> rightMAX
          continue
      elseif rightMAX>leftMAX
          fliplr(A(n,:))
      end
  end

However nothing changes in the array A

在 MATLAB Online 中打开

fliplr(A(n,:))

executes the fliplr. Then, there is no assignment statement, so it assigns the value to the variable "ans". It then looks and sees that there is no semi-colon after the expression, so it displays the value of the variable ans.

You did not make any change to the variable A.
