Unfortunately, this approach requires significant effort, and it isĭifficult to maintain. The logic built into the mex built script can be replaced byĪppropriate scripting of the CMakeLists.txt. Since mexfiles are simply native shared libraries with some specialįunctions, etc., it is possible to bypass the mex build scriptĬompletely. Try to emulate the logic built into the mex build script in CMakeLists.txt There are three basic approaches to utilize CMake for the process of Is loaded by by the MATLAB interpretor when the basename is found in The result of this process is a shared library (dll) mexfile that Structures, allocating memory in a way that it is controlled by MATLAB,Įtc. Primary MATLAB itself is written is C, and a variety of functions areĪvailable in the mex.h header for interrogating MATLAB data
Mex compiler for matlab 64 bit code#
The code mustĬontain a gateway function with specific syntax that MATLAB hooks into. The MEX compiler can process C, C++, or Fortran code. Shows the compiler and settings the build script is using. On Unix-like systems it is a shell script, although they have the sameĪllows you to setup the configuration file the mex script uses toĭetermine which compiler it will use, the flags it will pass, etc. How do you use CMake with MATLAB? Background on the MATLAB MEX "compiler" The are manyĪdvantages to organizing and controlling the build system in a simpleĪnd powerful way, which CMake can do, among other CMake provides aĬonfiguration system for finding libraries on systems. System allows you to recompile and link only the files that changeĭuring development and to perform parallel builds. Project is non-trivial, there are many advantages to using CMake. MEX compiler at the command line is all that you need. If you have a very small project that consists of only a single sourceĬode file that does not link to other libraries, then simply using the Why would you want to use CMake for creating MEX files? Instead, researchers should consider using Writing MEX files is often an attempt to address some of these Good for simple procedural scripting, is closed source, and has numerousīugs. Sees little use outside academia, has a language syntax that is only On the other hand, it isĮxtremely slow, has poor memory utilization, is prohibitively expensive, Throughout the academic, scientific community. Variety of functions, excellent documentation, and it is ubiquitous MATLAB is a language with good syntax for working with matrices, a General purpose scientific scripting language owned by Theĭetails of writing MEX files can be found in the MATLAB

MEX files are functions written in C or C++ that are callable in the
