MATLAB Compiler

Generated Code

This chapter investigates the generated header files, interface functions, and wrapper functions for the C MEX, stand-alone C and C++ targets, and C and C++ libraries.

When you use the MATLAB Compiler to compile an M-file, it generates these files:

• C or C++ code, depending on your target language (-L) specification
• Header file
• Wrapper file, depending on the -W option

The C or C++ code that is generated by the Compiler and the header file are independent of the final target type and target platform. That is, the C or C++ code and header file are identical no matter what the desired final output. The wrapper file provides the code necessary to support the output executable type. So, the wrapper file is different for each executable type.

This table shows the names of the files generated when you compile a generic M-file (file.m) for the MEX and stand-alone targets. The table also shows the files generated when you compile a set of files (filelist) for the library target.

Table 5-1: Compiler-Generated Files  

	C	C++
Header	file.h	file.hpp
Code	file.c	file.cpp
Main Wrapper (-W main)	file_main.c	file_main.cpp
MEX Wrapper (-W mex)	file_mex.c	N/A (C++ MEX-files are not supported.)
Simulink Wrapper (-W simulink)	file_simulink.c	N/A (C++ MEX-files are not supported.)
Library (-W lib:filelist)	filelist.c filelist.h filelist.exports filelist.mlib	filelist.cpp filelist.hpp filelist.mlib

Note    Many of the code snippets generated by the MATLAB Compiler that are used in this chapter use the -F page-width option to produce readable code that fits nicely on the book's printed page. For more information about the page-width option, see Formatting Compiler-Generated Code.
