How can I correctly apply this code -ffast-math in Matlab script? I want to apply GCC compiler -ffast-math option to increase CPU of the Matlab computer. This option is from Simulink® Real-Time™ models

Simulink Real-Time does not use gcc for the SpeedGoat target (or at least it does not use MinGW). It uses the development environment for BlackBerry® QNX® Neutrino® which is the QNX Momentics Tools Suite .

Hi Margarita,

As per my understanding, you are looking for methods to improve the performance of the code by adding the “-ffast-math”, flag for the GCC compiler, used in Simulink Real-Time.

One potential solution to optimize your code is to specify the “-ffast-math” flag in the make file generated for the application and then rebuild the application, this would result in faster optimized code.

Please, refer to the following link, for further information on different techniques to improve code Performance,

Hope this helps!
