It can also be # used: # # * run specific commands in Matlab # * declare Matlab unit test # * retrieve various information from Matlab (mex extensions, versions and # release queries, ...) # # The module supports the following components: # # * ``MX_LIBRARY``, ``ENG_LIBRARY`` and ``MAT_LIBRARY``: respectively the MX, # ENG and MAT libraries of Matlab # * ``MAIN_PROGRAM`` the Matlab binary program. # * ``MEX_COMPILER`` the MEX compiler. # * ``SIMULINK`` the Simulink environment. # # .. note:: # # The version given to the :command:`find_package` directive is the Matlab # **version**, which should not be confused with the Matlab *release* name # (eg. `R2014`). # The :command:`matlab_get_version_from_release_name` and # :command:`matlab_get_release_name_from_version` allow a mapping # from the release name to the version. # # The variable :variable:`Matlab_ROOT_DIR` may be specified in order to give # the path of the desired Matlab version. Otherwise, the behaviour is platform # specific: # # * Windows: The installed versions of Matlab are retrieved from the # Windows registry # * OS X: The installed versions of Matlab are given by the MATLAB # paths in ``/Application``. If no such application is found, it falls back # to the one that might be accessible from the PATH. # * Unix: The desired Matlab should be accessible from the PATH. # # Additional information is provided when :variable:`MATLAB_FIND_DEBUG` is set. # When a Matlab binary is found automatically and the ``MATLAB_VERSION`` # is not given, the version is queried from Matlab directly. # On Windows, it can make a window running Matlab appear. # # The mapping of the release names and the version of Matlab is performed by # defining pairs (name, version). The variable # :variable:`MATLAB_ADDITIONAL_VERSIONS` may be provided before the call to # the :command:`find_package` in order to handle additional versions. # # A Matlab scripts can be added to the set of tests using the # :command:`matlab_add_unit_test`. By default, the Matlab unit test framework # will be used (>= 2013a) to run this script, but regular ``.m`` files # returning an exit code can be used as well (0 indicating a success). # # Module Input Variables # ^^^^^^^^^^^^^^^^^^^^^^ # # Users or projects may set the following variables to configure the module # behaviour: # # :variable:`Matlab_ROOT_DIR` # the root of the Matlab installation. # :variable:`MATLAB_FIND_DEBUG` # outputs debug information # :variable:`MATLAB_ADDITIONAL_VERSIONS` # additional versions of Matlab for the automatic retrieval of the installed # versions. # # Variables defined by the module # ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ # # Result variables # """""""""""""""" # # ``Matlab_FOUND`` # ``TRUE`` if the Matlab installation is found, ``FALSE`` # otherwise. All variable below are defined if Matlab is found. # ``Matlab_ROOT_DIR`` # the final root of the Matlab installation determined by the FindMatlab # module. # ``Matlab_MAIN_PROGRAM`` # the Matlab binary program. Available only if the component ``MAIN_PROGRAM`` # is given in the :command:`find_package` directive. # ``Matlab_INCLUDE_DIRS`` # the path of the Matlab libraries headers # ``Matlab_MEX_LIBRARY`` # library for mex, always available. # ``Matlab_MX_LIBRARY`` # mx library of Matlab (arrays). Available only if the component # ``MX_LIBRARY`` has been requested. # ``Matlab_ENG_LIBRARY`` # Matlab engine library. Available only if the component ``ENG_LIBRARY`` # is requested. # ``Matlab_MAT_LIBRARY`` # Matlab matrix library. Available only if the component ``MAT_LIBRARY`` # is requested. # ``Matlab_LIBRARIES`` # the whole set of libraries of Matlab # ``Matlab_MEX_COMPILER`` # the mex compiler of Matlab. Currently not used. # Available only if the component ``MEX_COMPILER`` is asked # # Cached variables # """""""""""""""" # # ``Matlab_MEX_EXTENSION`` # the extension of the mex files for the current platform (given by Matlab). # ``Matlab_ROOT_DIR`` # the location of the root of the Matlab installation found. If this value # is changed by the user, the result variables are recomputed. # # Provided macros # ^^^^^^^^^^^^^^^ # # :command:`matlab_get_version_from_release_name` # returns the version from the release name # :command:`matlab_get_release_name_from_version` # returns the release name from the Matlab version # # Provided functions # ^^^^^^^^^^^^^^^^^^ # # :command:`matlab_add_mex` # adds a target compiling a MEX file. # :command:`matlab_add_unit_test` # adds a Matlab unit test file as a test to the project. # :command:`matlab_extract_all_installed_versions_from_registry` # parses the registry for all Matlab versions. Available on Windows only. # The part of the registry parsed is dependent on the host processor # :command:`matlab_get_all_valid_matlab_roots_from_registry` # returns all the possible Matlab paths, according to a previously # given list. Only the existing/accessible paths are kept. This is mainly # useful for the searching all possible Matlab installation. # :command:`matlab_get_mex_suffix` # returns the suffix to be used for the mex files # (platform/architecture dependent) # :command:`matlab_get_version_from_matlab_run` # returns the version of Matlab, given the full directory of the Matlab # program. # # # Known issues # ^^^^^^^^^^^^ # # **Symbol clash in a MEX target** # By default, every symbols inside a MEX # file defined with the command :command:`matlab_add_mex` have hidden # visibility, except for the entry point. This is the default behaviour of # the MEX compiler, which lowers the risk of symbol collision between the # libraries shipped with Matlab, and the libraries to which the MEX file is # linking to. This is also the default on Windows platforms. # # However, this is not sufficient in certain case, where for instance your # MEX file is linking against libraries that are already loaded by Matlab, # even if those libraries have different SONAMES. # A possible solution is to hide the symbols of the libraries to which the # MEX target is linking to. This can be achieved in GNU GCC compilers with # the linker option ``-Wl,--exclude-libs,ALL``. # # **Tests using GPU resources** # in case your MEX file is using the GPU and # in order to be able to run unit tests on this MEX file, the GPU resources # should be properly released by Matlab. A possible solution is to make # Matlab aware of the use of the GPU resources in the session, which can be # performed by a command such as ``D = gpuDevice()`` at the beginning of # the test script (or via a fixture). # # # Reference # ^^^^^^^^^ # # .. variable:: Matlab_ROOT_DIR # # The root folder of the Matlab installation.
