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: qlcon2vert.m
    path of file: ./repos/Robotics-Toolbox/rvcdlcs/src/thirdparty/cvxhull/polytopes
    
    the code of the file until where you have to start completion: function [varargout]=qlcon2vert(x0,varargin)
%A quicker version of lcon2vert that will skip some intensive steps when a
%point x0 in the relative interior of the polyhedron is known a priori.
%
%   [V,nr,nre]=qlcon2vert(x0, A,b,Aeq,beq,TOL)
%
%Here x0 is the known relative interior point. The rest of the input/output
%arguments are as in LCON2VERT.
%
%In the interest of speed, QLCON2VERT will perform minimal error checking,
%shifting the burden to the user of verifying that the input data has
%appropriate properties. In particular,  it will not try to verify that x0
%is in fact in the relative interior. By default also, qlcon2vert will skip the 
%boundedness test, and presume the  user knows the polyhedron to be bounded already.
%However, you can re-activate the boundedness test by calling with the syntax,
