This page provides instructions on how to install STIR for MATLAB. You will need STIR 3.1 or later for this to work (at present, use the [github version].

Introduction

You will need to use the instructions at Installing STIR with CMake. Here we will give more specific information.

These are instructions on how to install the STIR+MATLAB interface have been tested on a unix system with ubuntu 14.04. It relies on CmakeGui (as usual) and an extension of SWIG that has to be installed first.

Install SWIG

First, prepare your system with some packages 

 sudo apt-get install libtool automake autoconf autogen bison

Get a version of SWIG with preliminary MATLAB support 

 mkdir swig
 cd swig
 git clone https://github.com/KrisThielemans/swig.git swig_git

(you could try https://github.com/jaeandersson/swig.git instead which is already a bit more up-to-date) and checkout the right branch 

 cd swig_git	
 git checkout matlab

SWIG can now be installed 

 ./autogen.sh	
 cd ..
 mkdir build
 cd build	
 ../swig_git/configure	
 make
 sudo make install

Note that the install might fail at the end if it can't find yodl2man, but we don't care. Check with that we now have the right version (should say 3.0.3 or later) 

 swig -version

Install STIR

Follow the instructions on this page up to the point where you started cmake-gui.

  • press configure
  • press ok
  • set CMAKE_BUILD_TYPE to Release
  • enable BUILD_SWIG_MATLAB
  • If you want want to use openMP for acceleration, enable STIR_OPENMP
  • press configure
  • check that CMake found the correct SWIG file (not the system one). If it did, replace the SWIG variable and "configure" again
  • optionally adjust location of STIR-MATLAB files (MATLAB_DEST variable)
  • generate
  • close cmake-gui

Then either install STIR as usual 

 make    
 sudo make install

or you could build only the STIR+MATLAB first (just to see if it fails or not) 

 make stirMATLAB

Add path in MATLAB. E.g. 

 addpath /usr/local/matlab

Testing

There are a few tests in STIR/src/swig/test/matlab. Just execute these adding the directory where you installed it to your matlab path (e.g. if you choose /usr/local as your CMAKE_INSTALL_PREFIX, in MATLAB do "addpath /usr/local/matlab")

Examples
