This is one of my first experiences with embedded work, so bear with me on that.
I've got an STM32F4 Discovery Board. I've also got a Classification Learner (Ensemble KNN, but this question applies for any model) model.
The classification model takes a vector of 13 floating point numbers (MFCC's from an audio file) and classifies that vector as belonging to either a car, truck, or motorcycle.
I want to get this model onto my STM32F4 board and have it execute, but I'm not sure how to do that. The MATLAB coder outputs a MEX file, but I"m not sure if that's supported by STM32F4 or if I'm even on the right track. Does anyone have any insight on this? Thank you very much.

Hello,
I'm not an expert in this area, but you may want to check out Embedded Coder and Embedded Coder Support Package For STMicroelectronics. I also am doing a similar project (Keyword Spotting) using MFCC's and DTW algorithm. I also am hoping to use Embedded Coder.
This way, you can program your Discovery Board using Simulink with your functions.
