28. If linking fails 29. If loading fails 30. If running fails - segmentation violations Section 1: Introduction MEX-files This technical note provides a general overview of MEX-files and a detailed explanation of the external interface functio interface C or Fortran subroutines to MATLAB. MEX-files are a way to call your custom C or FORTRAN routines direct they were MATLAB built-in functions. MEX stands for MATLAB Executable. MEX-files are dynamically linked subroutines produced from C or Fortran source compiled, can be run from within MATLAB in the same way as MATLAB M-files or built-in functions. The external interf functionality to transfer data between MEX-files and MATLAB, and the ability to call MATLAB functions from C or Fortra The main reasons to write a MEX-file are: 1. The ability to call large existing C or FORTRAN routines directly from MATLAB without having to rewrite t 2. Speed; you can rewrite bottleneck computations (like for-loops) as a MEX-file for efficiency. MEX-files are not appropriate for all applications. MATLAB is a high-productivity system whos specialty is eliminating ti level programming in compiled languages like C or Fortran. In general, most programming should be done in MATLAB facility unless your application requires it. Section 2: Getting help You can learn more about MEX-files from the MATLAB External Interfaces Guide . If you already know how to write a M use the External Interfaces Function Reference . NOTE: The MathWorks Technical Support department does not have the resources needed to develop custom code fo application. If, however, a function is not behaving as you think it should, you can contact Technical Support for help. Section 3: System setup and configuration
