In general, it is not practical for us to offer complete technical support on the details of using any specific one of the large number of IDE environments our customers use. Using the MEX utility included with MATLAB may easier and will work just as well using an IDE is just an alternative. Note that you do not have to compile your MEX-file within an Integrated Development Environment (IDE). Section 6: Compiling MEX-files with Microsoft Visual Studio or another IDE Solution 1-175S9: Why does MATLAB hang or generate an error when I try to run mex -setup or mbuild -setup?.Solution 1-18TTY: Why do I get the error "Error: Compile of �yprime.c�failed" when compiling the yprime.c example?.The Documentation section on Building MEX Files: What You Need to Build MEX-Files.The following resources should offer some insight if you have trouble with any of the above steps. Section 5: Troubleshooting system configuration problems This may give more information about why the compilation is failing.įor an example of C++ MEX-File, see Section 25: C++ MEX-file Overview below. This will produce a lot of output (v is for verbose) that shows the compiling and linking process. If you do not get this result, or you receive error messages when trying to compile, add a -v flag to your compilation command. You should get the following output: ans= This creates a MEX-file that can be used at the command prompt like any M-file. If you are using Fortran, type the following at the MATLAB prompt: mex yprime.f yprimefg.f If you are using C, type the following at the MATLAB prompt to compile the file: mex yprime.c Try compiling our sample MEX-file, yprime.c found in the /extern/examples/mex directory. Section 4: Testing your system with example MEX-files After answering these questions, a MEX options file is created that gives MATLAB all of the information it needs to use your compiler during compilation.

When you run this command, a series of questions are asked regarding the location of the C, C++ or Fortran compiler you would like to use to compile your code. In order to do this, run the following command from the MATLAB command prompt: mex -setup Once you have verified that you are using a supported C, C++ or FORTRAN compiler, you are ready to configure your system to build MEX-files. The MathWorks also maintains a list of compilers supported by MATLAB. You can specify which compiler you want to use. An options file is provided for each supported compiler. MATLAB supports the use of a variety of compilers for building MEX-files. Section 3: System setup and configuration If, however, a function is not behaving as you think it should, you can contact Technical Support for help.

Note: The MathWorks Technical Support department does not have the resources needed to develop custom code for each specialized application.

If you already know how to write a MEX-file, you can also use the External Interfaces Function Reference. You can learn more about MEX-files from the MATLAB External Interfaces Guide. Do not use the MEX facility unless your application requires it. In general, most programming should be done in MATLAB. MATLAB is a high-productivity system whose specialty is eliminating time-consuming, low-level programming in compiled languages like C, C++ or Fortran. MEX-files are not appropriate for all applications.
MEX-files are dynamically linked subroutines produced from C, C++ or Fortran source code that, when compiled, can be run from within MATLAB in the same way as MATLAB M-files or built-in functions. MEX-files are a way to call your custom C, C++ or FORTRAN routines directly from MATLAB as if they were MATLAB built-in functions. This technical note provides a general overview of MEX-files and a detailed explanation of the external interface functions that allow you to interface C, C++ or Fortran subroutines to MATLAB.
