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: htkread.m
    path of file: ./repos/deeplearningsourceseparation/tools/htk_features
    
    the code of the file until where you have to start completion: function [ DATA, HTKCode ] = htkread( Filename )
% [ DATA, HTKCode ] = htkread( Filename )
%
% Read DATA from possibly compressed HTK format file.
%
% Filename (string) - Name of the file to read from
% DATA (nSamp x NUMCOFS) - Output data array
% HTKCode - HTKCode describing file contents
%

    
function [ DATA, HTKCode ] = htkread( Filename )
% [ DATA, HTKCode ] = htkread( Filename )
%
% Read DATA from possibly compressed HTK format file.
%
% Filename (string) - Name of the file to read from
% DATA (nSamp x NUMCOFS) - Output data array
% HTKCode - HTKCode describing file contents
%
% Compression is handled using the algorithm in 5.10 of the HTKBook.
% CRC is not implemented.

fid=fopen(Filename,'r','b');
