The MEX file contains only one function or subroutine. In a future version of MATLAB ®, the default api option will change to use the interleaved complex API (-R2018a). MathWorks recommends that you create MEX files and update existing MEX files to use the interleaved complex API. Alternatively, use the MX_HAS_INTERLEAVED_COMPLEX macro to ensure the desired behavior across versions of MATLAB. To create a MEX function, write your program using MATLAB APIs, then build it using the mex command. The APIs provide these features: Call MATLAB functions from the MEX function. Integrate seamlessly into MATLAB, getting inputs from and returning results to MATLAB.

Calling MATLAB functions from a mex routine will slow things down. How much depends on what you are doing, the size of the variables, and how often you make the calls. There is overhead in the call itself, and also if your are calling from an Engine typically a deep data copy both ways is involved.

MEX-files are a way to call your custom C or FORTRAN routines directly from MATLAB as if they were MATLAB built-in functions. Mex-files can be called exactly like M-functions in MATLAB. Here, all code examples will be presented in C. 2007-10-22 Maria Axelsson, Centre for Image Analysis Reasons for MEX-files MATLAB ® provides an API that uses modern C++ semantics and design patterns, the MATLAB Data API. MathWorks recommends that you create MEX functions with this API. For more information, see C++ MEX Applications. If your MEX functions must run in MATLAB R2017b or earlier, then you must use the C Matrix API functions in your C++ applications. – Routines prefixed with mex perform operations in the MATLAB environment • mex routines are only available in MEX-functions, e.g., #include "mex.h" int mexEvalString(const char *command); command – a string containing the MATLAB command to execute By creating a MATLAB interface in my code, then compiling my code into a MEX file, my obtuse code becomes both fast and easy to use, and as a result I can run my experiments and plot the results using MATLAB's nice plotting tools. Different people may have different reasons for resorting to MEX files, but it is an important tool for almost any Jun 09, 2016 · I have done a bit of searching on google and it turns out that mex allows Matlab to read code written in C/C++ ? I have also tried to use the cmd line in matlab to setup mex but it says "No supported compiler or SDK was found." To create a MEX function, write your program using MATLAB APIs, then build it using the mex command.

A MEX function behaves just like a MATLAB script or function. To call a MEX function, use the name of the MEX file, without the file extension. The MEX file contains only one function or subroutine. In a future version of MATLAB ®, the default api option will change to use the interleaved complex API (-R2018a). MathWorks recommends that you create MEX files and update existing MEX files to use the interleaved complex API. Alternatively, use the MX_HAS_INTERLEAVED_COMPLEX macro to ensure the desired behavior across versions of MATLAB. A MEX file is a function, created in MATLAB, that calls a C/C++ program or a Fortran subroutine.

Monte Carlo eXtreme (MCX) MCX is a Monte Carlo simulation software for static or time-resolved photon transport in 3D media. I mexcuda filenames compiles and links source files into a shared library called a MEX-file, executable from within MATLAB ®.The function compiles MEX-files written using the CUDA ® C++ framework with the NVIDIA ® nvcc compiler, allowing the files to define and launch GPU kernels. In addition, the mexcuda function exposes the GPU MEX API to allow the MEX-file to read and write gpuArrays. Note: This document applies to Intel® MKL 2017 and MATLAB* R2015b running on Windows*. How can I configure MATLAB to run the Intel MKL 2017 at start-up?
