You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: comb_sort.m
    path of file: ./repos/MATLAB-Octave/algorithms/sorting
    
    the code of the file until where you have to start completion: %This function sorts the input array in ascending order using the Comb Sort algorithm
%For details, refer https://en.wikipedia.org/wiki/Comb
    
function sorts the input array in ascending order using the Comb Sort algorithm
%For details, refer https://en.wikipedia.org/wiki/Comb_sort

function y = comb_sort(array)
            
len = length(array);
k = len;
isSwapped = true;
% value of shrink should be greater than 1
shrink = 1.4; 
while ((k > 1) || (isSwapped == true))    
    k = max(floor(k / shrink),1);   
    % Bubble sort with given value of k
    i = 1;
    isSwapped = false;
    while ((i + k) <= len)
        if (array(i) > array(i + k))
            array = swap(array,i,i + k);
            isSwapped = true;
        end
