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: Huff06.m
    path of file: ./repos/microshift_compression/verilog code/matlab_files/Toolkits/arithmetic encoding
    
    the code of the file until where you have to start completion: function varargout = Huff06(xC, ArgLevel, ArgSpeed)
% Huff06      Huffman encoder/decoder with (or without) recursive s
    
function x = DecodeVector
global y Byte BitPos
MaxL=50000;      % as in the EncodeVector function (line 216)
if GetBit
   x1=DecodeVector;
   x2=DecodeVector;
   L=length(x1)+length(x2);
   if (L>MaxL)
      x=[x1(:);x2(:)];
   else
      xm=median([x1;x2]);
      x=zeros(L,1);
      x(1)=x2(1);
      i1=0;i2=1;
      for i=2:L
         if (x(i-1) <= xm) 
            i1=i1+1; x(i)=x1(i1);
         else
            i2=i2+1; x(i)=x2(i2);
         end
