What Are Code Acceleration and Code Generation from MATLAB?

In many cases, you may want your code to run faster and more efficiently. Code acceleration provides optimizations for accelerating fixed-point algorithms through MEX file generation. In Fixed-Point Toolbox the fiaccel function converts your MATLAB code to a MEX function and can greatly accelerate the execution speed of your fixed-point algorithms.

Code generation creates efficient, production-quality C/C++ code for desktop and embedded applications. There are several ways to use Fixed-Point Toolbox software to generate C/C++ code.

Use...	To...	Requires...	See...
MATLAB® Coder™ (codegen) function	Automatically convert MATLAB code to C/C++ code	MATLAB Coder code generation software license	Generating C Code from MATLAB Code at the Command Line in the MATLAB Coder documentation
MATLAB Function	Use MATLAB code in your Simulink models that generate embeddable C/C++ code	Simulink license	Using the MATLAB Function Block in the Simulink documentation

MATLAB code generation supports variable-size arrays and matrices with known upper bounds. To learn more about using variable-size signals, see What Is Variable-Size Data? in the Code Generation for MATLAB documentation.
