matlab examples

Some examples of using the Matlab libraries with cmake and c++

Matlab configuration notes

• Set Matlab_ROOT_DIR to point cmake to the right installation
• Ensure that matlab is found on the PATH when executing, as the wrapper call uses the cmd line .. as strange as that is
• FindMatlab.cmake actually calls matlab to identify the version number of the application, failing if it cant
  • So in other words your license needs to be available to run CMake
• Turn on MATLAB_FIND_DEBUG for help
  • set(MATLAB_FIND_DEBUG true)
• FindMatlab.cmake uses a hardcoded list of version numbers when it searches for matlab
  • You can add a new version with MATLAB_ADDITIONAL_VERSIONS
• Matlab shared libraries are not versioned and may conflict with system libraries when linking
• It appears R2015b may not have the linking issues that R2017a has
• It also appears that using the standard matlab finder resolves linking issues all together?
  • or at least hacking libs out of path is not needed anyways

Adding all current Matlab versions to CMake 3.5.1

If on Ubuntu 16.04 and CMake 3.5.1, only versions up to "R2015b=8.6" will be found by default (source)

To add versions up to the latest as of 08/2017, add this before find_library.

•   set(MATLAB_ADDITIONAL_VERSIONS 
        "R2017a=9.2"
        "R2016b=9.1"
        "R2016a=9.0")
