This provides a language binding of libbiosig to Matlab and Octave. 
and some speedier c-mex implementation for some matlab code. 
Basically, mex-files for loading biosig data are provided.
- mexSLOAD.mex* loads the whole file (header and data). 
- mexSOPEN.mex* reads only the header information. 
- mexSSAVE.mex* saves data into various biosig format 
   the list of supported formats is shown here: http://pub.ist.ac.at/~schloegl/biosig/TESTED
- accovf_mex.mex* compute auto- and cross-correlation function for MOD method
- sumskipnan_mex.mex* covm_mex.mex*

COMPILATION: 

== Octave on Linux =======================
On Linux platforms the compilation is straight forward. A prerequisite is
libbiosig (with its dependencies).
     make libbiosig && sudo make install

Generate and install mexbiosig-package
     make mexbiosig
     sudo make install_mexbiosig

== Octave on MacOSX =======================
You need to have homebrew  (for details see http://brew.sh)

  # 1) Install XCode from App Store
  xcode-select --install

  # 2) install homebrew
  ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)"

  # 3) Install prerequisites and recommendations for Octave
  brew install caskroom/cask/brew-cask
  brew cask install xquartz
  brew cask install mactex
  brew install curl

  # 4) install Octave
  brew tap homebrew/science
  export PATH="$PATH:/usr/texbin"
  brew install octave --with-docs

and install biosig
   brew tap schloegl/biosig
   brew install mexbiosig

== Octave on Window (MXE-Octave) =======================
   # 1) Download and install Octave 4.0.0
	https://ftp.gnu.org/gnu/octave/windows/
   # 2) Get biosig sources
	either with git
	    git clone git://git.code.sf.net/p/biosig/code biosig-code
	or source package from http://biosig.sourceforge.net/download.html
	    libbiosig-X.Y.Z.src.tar.gz (requires version 1.7.3 or later)
   # 3) Start Octave and change directory to
	.../biosig4c++/
   # 4) Make and install libbiosig
	system('make && make install')
   # 5) Generate mexbiosig pkg
	system('make mexbiosig')
   # 6) Install mexbiosig-package
	pkg install mex/mexbiosig-1.7.3.tar.gz


== Matlab on Linux, MacOSX  =======================
Prerequisites:
    sudo apt-get install zlib1g-dev libsuitesparse-dev
Edit Makefile and set the correct path to Matlab:
The mex files for Matlab are generated with 
	MATLABDIR=/usr/local/MATLAB/R2014b make mex4m


== Matlab v7.11 for Win32 ================
Compilation was successful using the mingw-cross-env on linux to generate Win32/mex files. 
GnuMex/Mingw must be installed together with Matlab on windows.
The gnumex libraries must be copied to the linux machine having MinGW-Cross-env installed. 
Adapt the Makefile and run 
	make mexw32 mexw64
