MATLAB: Are graphics supported in MATLAB Compiler generated shared libraries

compilercsglsharedlibdllgraphicslibhglibrarylinkMATLAB C/C++ Graphics Librarysharedsupportunsupported

Using MATLAB Compiler 3.0 (R13), I am able to generate a shared library that links to the Graphics Library using the following syntax:

mcc -t -L C -W libhg:my_lib -T link:lib -h my_mfile.m

Is this type of library officially supported?

As of MATLAB Compiler 4.0 (R14), graphics are officially supported in Compiler generated shared libraries. M-functions that use graphics can be compiled into a C shared library using the "-B csharedlib" option, just like compiling a non-graphical M-function into a C shared library. If you are using a previous version of MATLAB Compiler, see the following:

For MATLAB 6.5 (R13), The MATLAB C/C++ Graphics Library is only officially supported for use in MATLAB Compiler generated executables.

Although generated shared libraries that use graphics may in some cases function without error, the MATLAB C/C++ Graphics Library has not been fully tested for use in a MATLAB Compiler generated shared library and is not guaranteed to work. We are unable to provide assistance for cases where such a library does not work.

Note that MATLAB COM Builder allows you to generate shared libraries which include MATLAB graphics routines in the form of a COM (Common Object Model) object.

The MATLAB C/C++ Graphics Library has not been fully tested for use in a MATLAB Compiler generated shared library. Also, using the Graphics Library in a shared library is not officially supported by MathWorks. The MATLAB C/C++ Graphics Library is only supported for use in MATLAB Compiler generated executables.

To work around this issue, initalize both shared libraries at the beginning of your application and terminate them both at the end. The order is shown in the pseudocode below:

 void main(int argc, char **argv) 
 {
         InitializeLib1();
         InitializeLib2();
            ... /*call lib1 and lib2 functions*/
         TerminateLib2();
         TerminateLib1();
 }

MATLAB: Are the MATLAB Math and Graphics Libraries supported anymore

Since MATLAB Compiler 3.0 (R13), the MATLAB Math and Graphics Libraries have been unsupported. This is why there is no longer any documentation about them.

If you wish to call MATLAB functionality from a C/C++ program, you should compile your MATLAB code to a shared library or COM object using the MATLAB Compiler or the MATLAB Builder for COM.
