ipopt-matlab-interface-cmake

Rationale

IPOPT is distributed with an own MATLAB interface, that however is outdated and is not working with recent MATLAB versions. For this reason, this repo contains a copy of the mexIPOPT MATLAB interface to IPOPT, with its build system modified to use CMake to build the bindings both for MATLAB and for Octave.

Installation

Build this project as any CMake-based project, for example on *nix system :

git clone https://github.com/traversaro/ipopt-matlab-interface-cmake
cd ipopt-matlab-interface-cmake
# Enable the IPOPT_USES_MATLAB and IPOPT_USES_OCTAVE depending if MATLAB or Octave is available 
cmake -DCMAKE_INSTALL_PREFIX=./install -DIPOPT_USES_MATLAB=ON -DIPOPT_USES_OCTAVE=ON ..
cmake --build . 
cmake --build . --target install 

We use the CMake's FindMatlab.cmake and a local FindOctave.cmake to find MATLAB and Octave. In both cases, CMake should find the programs if the matlab and octave programs are available in the PATH.

Usage

Once you installed the bindings, just add ${CMAKE_INSTALL_PREFIX}/mex to the MATLAB path if you are using MATLAB and add ${CMAKE_INSTALL_PREFIX}/octave to the Octave PATH if you are using Octave.

To use the bindings, check the documentation available typing help ipopt in the MATLAB/Octave shell, or check the examples available in the mexIPOPT repository.

Import a new version of mexIPOPT (only for mantainers)

If you want to update the version of mexIPOPT contained in this repo, please update the GIT_TAG CMake variable in https://github.com/traversaro/ipopt-matlab-interface-cmake/blob/master/CMakeLists.txt#L39 and execute the admin-update-ipopt-vendored-code target. This will copy the necessary code in the extern directory.
