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: hikmeanspush.m
    path of file: ./repos/CS_MoCo_LAB/reconstruction/matlab/CS_LAB_matlab/utils/utils_SURF/toolbox/noprefix
    
    the code of the file until where you have to start completion: function varargout = hikmeanspush(varargin)
% VL_HIKMEANSPUSH   Push data down an integer K-means tree
%   PATH = VL_HIKMEANSPUSH(TREE,X) quanizes the data X with the

    
function varargout = hikmeanspush(varargin)
% VL_HIKMEANSPUSH   Push data down an integer K-means tree
%   PATH = VL_HIKMEANSPUSH(TREE,X) quanizes the data X with the
%   hierachical integer K-means tree TREE. This is obtained by
%   calculating the path of each datum from the root of TREE down to a
%   leaf. Here X has a datum for each column and each column of PATH
%   represents the corresponding root-to-leaf path.
%
%   Example::
%     PATH(:,1) = [2 1 4] means that the first datum follows
%     the branches number 2, 1 and 4 starting from the root of the
%     HIKM tree end
