creating a while loop updating values that doesnt equal mode in matlab

Here is an example code snippet that demonstrates how to create a while loop that updates values in an array based on a conditional statement that checks if the current value is not equal to the mode of the array.

main.m
% Initialize array
arr = [2 5 5 5 8 9 9];

% Get mode of array
mode_val = mode(arr);

% Initialize loop counter
i = 1;

% Loop until every element in the array is checked
while i <= length(arr)
    
    % Check if current element is not equal to mode
    if arr(i) ~= mode_val
        
        % Update element value
        arr(i) = arr(i) + 1;
    end
    
    % Increment loop counter
    i = i + 1;
end

This code checks each element in the array arr and updates the value if it is not equal to the mode of the array (mode_val). The loop continues until every element in the array has been checked. The if statement checks if the current element is not equal to the mode, and if so, updates the value by adding 1.

Note that this code could be vectorized, but a while loop was specifically requested.
