Generating Code
C/C++ code generation is the core functionality of MATLAB®
Coder™. Generate code from the app, which you can open with coder, or from the command line, by
using the codegen function. The app provides
step-by-step guidance through the code generation process, including guidance around
best practices, and clear visual aids for the many code generation settings and
options. The command line workflow enables simple, repeatable, and efficient
initiation of code generation. The code generation workflow supports many different
data types, including variable-size data and global data. The workflow also supports
multiple entry-point (top-level) functions, multisignature MEX function generation,
and customization of fundamental properties such as the array layout and array
indexing of the generated code. In addition, you can generate code that uses key C++
language features such as classes, namespaces, and function overloading.
