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: vl_aibcut.m
    path of file: ./repos/CS_MoCo_LAB/reconstruction/matlab/CS_LAB_matlab/utils/utils_SURF/toolbox/aib
    
    the code of the file until where you have to start completion: function [cut, map, short] = vl_aibcut(parents, n)

    
function [cut, map, short] = vl_aibcut(parents, n)
% VL_AIBCUT  Cut VL_AIB tree
%  CUT = VL_AIBCUT(PARENTS, N) cuts the binary merge tree PARENTS and
%  returns a cut CUT of N nodes. The format of PARENTS is the same
%  used by the VL_AIB() function.
%
%  A cut is a set of N nodes such that no node is a descend
