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.

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.
