FindMatlab
|
|
----------
|
|
|
|
Finds Matlab or Matlab Compiler Runtime (MCR) and provides Matlab tools,
|
|
libraries and compilers to CMake.
|
|
|
|
This package primary purpose is to find the libraries associated with Matlab
|
|
or the MCR in order to be able to build Matlab extensions (mex files). It
|
|
can also be used:
|
|
|
|
* to run specific commands in Matlab in case Matlab is available
|
|
* for declaring Matlab unit test
|
|
* to retrieve various information from Matlab (mex extensions, versions and
|
|
release queries, ...)
|
|
|
|
.. versionadded:: 3.12
|
|
Added Matlab Compiler Runtime (MCR) support.
|
|
|
|
The module supports the following components:
|
|
|
|
* ``ENG_LIBRARY`` and ``MAT_LIBRARY``: respectively the ``ENG`` and ``MAT``
|
|
libraries of Matlab
|
|
* ``MAIN_PROGRAM`` the Matlab binary program. Note that this component is not
|
|
available on the MCR version, and will yield an error if the MCR is found
|
|
instead of the regular Matlab installation.
|
|
* ``MEX_COMPILER`` the MEX compiler.
|
|
* ``MCC_COMPILER`` the MCC compiler, included with the Matlab Compiler add-on.
|
|
* ``SIMULINK`` the Simulink environment.
|
|
|
|
.. versionadded:: 3.7
|
|
Added the ``MAT_LIBRARY`` component.
|
|
|
|
.. versionadded:: 3.13
|
|
Added the ``ENGINE_LIBRARY``, ``DATAARRAY_LIBRARY`` and ``MCC_COMPILER``
|
|
components.
|
|
|
|
.. versionchanged:: 3.14
|
|
Removed the ``MX_LIBRARY``, ``ENGINE_LIBRARY`` and ``DATAARRAY_LIBRARY``
|
|
components. These libraries are found unconditionally.
|
|
|
|
.. 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` provide a mapping
|
|
between the release name and the version.
|
|
|
|
The variable :variable:`Matlab_ROOT_DIR` may be specified in order to give
|
|
the path of the desired Matlab version. Otherwise, the behavior is platform
|
|
specific:
|
|
|
|
* Windows: The installed versions of Matlab/MCR are retrieved from the
|
|
Windows registry
|
|
* OS X: The installed versions of Matlab/MCR are given by the MATLAB
|
|
default installation 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``. This does
|
|
not work for MCR installation and :variable:`Matlab_ROOT_DIR` should be
|
|
specified on this platform.
|
|
|
|
Additional information is provided when :variable:`MATLAB_FIND_DEBUG` is set.
|
|
When a Matlab/MCR installation is found automatically and the ``MATLAB_VERSION``
|
|
is not given, the version is queried from Matlab directly (on Windows this
|
|
may pop up a Matlab window) or from the MCR installation.
|
|
|
|
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).
|
|

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 behavior 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. If set before the call to
|
|
:command:`find_package`, the module will look for the components in that
|
|
path. If not set, then an automatic search of Matlab
|
|
will be performed. If set, it should point to a valid version of Matlab.
|
|
|
|
.. variable:: MATLAB_FIND_DEBUG
|
|
|
|
If set, the lookup of Matlab and the intermediate configuration steps are
|
|
outputted to the console.
|
|
|
|
.. variable:: MATLAB_ADDITIONAL_VERSIONS
|
|
|
|
If set, specifies additional versions of Matlab that may be looked for.
|
|
The variable should be a list of strings, organized by pairs of release
|
|
name and versions, such as follows::
|
|
|
|
set(MATLAB_ADDITIONAL_VERSIONS
|
|
"release_name1=corresponding_version1"
|
|
"release_name2=corresponding_version2"
|
|
...
|
|
)
|
|
|
|
Example::
|
|
|
|
set(MATLAB_ADDITIONAL_VERSIONS
|
|
"R2013b=8.2"
|
|
"R2013a=8.1"
|
|
"R2012b=8.0")
|
|
|
|
The order of entries in this list matters when several versions of
|
|
Matlab are installed. The priority is set according to the ordering in
|
|
this list.

.. command:: matlab_add_unit_test
|
|
|
|
Adds a Matlab unit test to the test set of cmake/ctest.
|
|
This command requires the component ``MAIN_PROGRAM`` and hence is not
|
|
available for an MCR installation.
|
|
|
|
The unit test uses the Matlab unittest framework (default, available
|
|
starting Matlab 2013b+) except if the option ``NO_UNITTEST_FRAMEWORK``
|
|
is given.
|
|
|
|
The function expects one Matlab test script file to be given.
|
|
In the case ``NO_UNITTEST_FRAMEWORK`` is given, the unittest script file
|
|
should contain the script to be run, plus an exit command with the exit
|
|
value. This exit value will be passed to the ctest framework (0 success,
|
|
non 0 failure). Additional arguments accepted by :command:`add_test` can be
|
|
passed through ``TEST_ARGS`` (eg. ``CONFIGURATION <config> ...``).

The function arguments are:

|
|
|
``NAME``
|
|
name of the unittest in ctest.
|
|
``UNITTEST_FILE``
|
|
the matlab unittest file. Its path will be automatically
|
|
added to the Matlab path.
|
|
``CUSTOM_TEST_COMMAND``
|
|
Matlab script command to run as the test.
|
|
If this is not set, then the following is run:
|
|
``runtests('matlab_file_name'), exit(max([ans(1,:).Failed]))``
|
|
where ``matlab_file_name`` is the ``UNITTEST_FILE`` without the extension.
|
|
``UNITTEST_PRECOMMAND``
|
|
Matlab script command to be ran before the file
|
|
containing the test (eg. GPU device initialization based on CMake
|
|
variables).
|
|
``TIMEOUT``
|
|
the test timeout in seconds. Defaults to 180 seconds as the
|
|
Matlab unit test may hang.
|
|
``ADDITIONAL_PATH``
|
|
a list of paths to add to the Matlab path prior to
|
|
running the unit test.
|
|
``MATLAB_ADDITIONAL_STARTUP_OPTIONS``
|
|
a list of additional option in order
|
|
to run Matlab from the command line.
|
|
``-nosplash -nodesktop -nodisplay`` are always added.
|
|
``TEST_ARGS``
|
|
Additional options provided to the add_test command. These
|
|
options are added to the default options (eg. "CONFIGURATIONS Release")
|
|
``NO_UNITTEST_FRAMEWORK``
|
|
when set, indicates that the test should not
|
|
use the unittest framework of Matlab (available for versions >= R2013a).
|
|
``WORKING_DIRECTORY``
|
|
This will be the working directory for the test. If specified it will
|
|
also be the output directory used for the log file of the test run.
|
|
If not specified the temporary directory ``${CMAKE_BINARY_DIR}/Matlab`` will
|
|
be used as the working directory and the log location.

.. command:: matlab_add_mex
|
|
|
|
Adds a Matlab MEX target.
|
|
This commands compiles the given sources with the current tool-chain in
|
|
order to produce a MEX file. The final name of the produced output may be
|
|
specified, as well as additional link libraries, and a documentation entry
|
|
for the MEX file. Remaining arguments of the call are passed to the
|
|
:command:`add_library` or :command:`add_executable` command.

|
|
|
|
``NAME``
|
|
name of the target.
|
|
``SRC``
|
|
list of source files.
|
|
``LINK_TO``
|
|
a list of additional link dependencies. The target links to ``libmex``
|
|
and ``libmx`` by default, unless the
|
|
``NO_IMPLICIT_LINK_TO_MATLAB_LIBRARIES`` option is passed.
|
|
``OUTPUT_NAME``
|
|
if given, overrides the default name. The default name is
|
|
the name of the target without any prefix and
|
|
with ``Matlab_MEX_EXTENSION`` suffix.
|
|
``DOCUMENTATION``
|
|
if given, the file ``file.txt`` will be considered as
|
|
being the documentation file for the MEX file. This file is copied into
|
|
the same folder without any processing, with the same name as the final
|
|
mex file, and with extension `.m`. In that case, typing ``help <name>``
|
|
in Matlab prints the documentation contained in this file.
|
|
``R2017b`` or ``R2018a``
|
|
.. versionadded:: 3.14
|
|
|
|
May be given to specify the version of the C API
|
|
to use: ``R2017b`` specifies the traditional (separate complex) C API,
|
|
and corresponds to the ``-R2017b`` flag for the `mex` command. ``R2018a``
|
|
specifies the new interleaved complex C API, and corresponds to the
|
|
``-R2018a`` flag for the `mex` command. Ignored if MATLAB version prior
|
|
to R2018a. Defaults to ``R2017b``.
|
|
|
|
``MODULE`` or ``SHARED``
|
|
.. versionadded:: 3.7
|
|
|
|
May be given to specify the type of library to be
|
|
created.
|
|
|
|
``EXECUTABLE``
|
|
.. versionadded:: 3.7
|
|
|
|
May be given to create an executable instead of
|
|
a library. If no type is given explicitly, the type is ``SHARED``.
|
|
``EXCLUDE_FROM_ALL``
|
|
This option has the same meaning as for :prop_tgt:`EXCLUDE_FROM_ALL` and
|
|
is forwarded to :command:`add_library` or :command:`add_executable`
|
|
commands.
|
|
``NO_IMPLICIT_LINK_TO_MATLAB_LIBRARIES``
|
|
.. versionadded:: 3.24
|
|
|
|
This option permits to disable the automatic linking of MATLAB
|
|
libraries, so that only the libraries that are actually required can be
|
|
linked via the ``LINK_TO`` option.
|
|
|
|
The documentation file is not processed and should be in the following
