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 building. In Fixed-Point Designer™ 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 Designer software to generate C/C++ code.

Use...	To...	Requires...	See...
MATLAB Coder™ (codegen (MATLAB Coder)) function	Automatically convert MATLAB code to C/C++ code	MATLAB Coder code generation software license	Generate C Code at the Command Line (MATLAB Coder)
MATLAB Function	Use MATLAB code in your Simulink® models that generate embeddable C/C++ code	Simulink license	Implement MATLAB Functions in Simulink with MATLAB Function Blocks

MATLAB code generation supports variable-size arrays and matrices with known upper bounds. To learn more about using variable-size signals, see Code Generation for Variable-Size Arrays.
