Generate C and C++ code from MATLAB code


MATLAB Coder™ generates C and C++ code from MATLAB® code for a variety of hardware platforms, from desktop systems to embedded hardware. It supports most of the MATLAB language and a wide range of toolboxes. You can integrate the generated code into your projects as source code, static libraries, or dynamic libraries. The generated code is readable and portable. You can incorporate your existing C code and libraries to get the ultimate efficiency for the key parts of your algorithm, or to reuse code you trust. You can also package the generated code as a MEX-function for use in the MATLAB environment for verification or acceleration.

Embedded Coder® enhances MATLAB Coder for production use with support for code customization, target-specific optimizations, code traceability, and software-in-the-loop (SIL) and processor-in-the-loop (PIL) verification.

To deploy MATLAB programs as standalone applications, use MATLAB Compiler™ and to generate software components for integration with other programming languages, use MATLAB Compiler SDK™

Get Started:

Run Anywhere

Generate readable and portable ANSI C source code. Deploy code royalty-free.

Deploy Algorithms Royalty-Free

Use any C compiler to compile and run your generated code on any hardware, from desktop systems to mobile devices to embedded hardware. The generated code is royalty-free—deploy it in commercial applications to your customers at no charge.

Move from Prototyping to Production

Use MATLAB Coder with Embedded Coder® to generate code that takes advantage of processor-specific intrinsics that can execute faster than standard ANSI/ISO C/C++ code.

Integrate with Software

Reuse MATLAB algorithms as C code within your software environment.

Generate Code with Simple Interfaces That Are Easy to Integrate

Generated code uses C types in a natural way, simplifying integration with external code. You can integrate generated code as source code or libraries. Trusted C libraries or components can be brought into MATLAB for higher-fidelity testing and are automatically called from generated code as well.

Optimize the Performance of Generated Code

Apply optimizations to adjust tradeoffs between execution speed, memory usage, readability, and portability. Use profiling tools to identify bottlenecks. To further boost performance, generate multicore OpenMP code and call optimized libraries such as LAPACK, BLAS, and FFTW when available.

Reuse MATLAB Tests on Generated Code Prior to Integration

Reuse existing MATLAB tests to verify the behavior of generated code in the interactive MATLAB environment. Use the MATLAB unit test framework to quickly develop a rich set of regression tests that can be used to verify the generated C code.

Accelerate Algorithms

Generate C code and compile it for use inside MATLAB.

Accelerate Algorithms on CPUs

You can call generated code as MEX functions from your MATLAB code to speed execution, though performance will vary depending on the nature of your MATLAB code. You can profile generated MEX functions to identify bottlenecks and focus your optimization efforts.
