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: volmap2mesh.m
    path of file: ./repos/iso2mesh
    
    the code of the file until where you have to start completion: function [node,elem,face]=volmap2mesh(img,ix,iy,iz,elemnum,maxvol,thickness,Amat,Bvec)

% input: 
%        img, ix,iy,iz, elemnum and  maxvol: see vol2mesh.m
%        thickness: scale z-dimension of the mesh to specified thickness, 
%                   if thickness==0, scaling is bypassed
%        Amat: a 3x3 transformation matrix
%        Bvec: a 3x1 vector
%        Amat and Bvec maps the image index space to real world coordnate system by
