Statistics and Machine Learning Toolbox™ 함수에 대한 C/C++ 코드 및 MEX 함수 생성

MATLAB^® Coder™는 코드 생성을 지원하는 Statistics and Machine Learning Toolbox 함수에서, 읽을 수 있고 이식 가능한 C 및 C++ 코드를 생성합니다. 예를 들어, 코드 생성을 사용하여 MATLAB을 실행할 수 없는 하드웨어 장치에 훈련된 서포트 벡터 머신(SVM) 분류 모델을 배포해 이 장치에서 새 관측값을 분류할 수 있습니다.

여러 가지 방법으로 다음 함수에 대한 C/C++ 코드를 생성할 수 있습니다.

머신러닝 모델의 객체 함수에 대해서는 saveLearnerForCoder, loadLearnerForCoder, codegen (MATLAB Coder)을 사용합니다.
머신러닝 모델의 predict 및 update 객체 함수에 대해서는 learnerCoderConfigurer로 생성된 코더 구성기를 사용합니다. 이 구성기를 사용하여 코드 생성 옵션을 구성하고 생성된 코드에서 모델 파라미터를 업데이트하십시오.
코드 생성을 지원하는 다른 함수에 대해서는 codegen을 사용합니다.

일부 머신러닝 모델의 예측을 위해 고정소수점 C/C++ 코드를 생성할 수도 있습니다. 이 유형의 코드를 생성하려면 Fixed-Point Designer™가 필요합니다.

머신러닝 모델의 예측을 Simulink^®에 통합하려면 Statistics and Machine Learning Toolbox 라이브러리에서 MATLAB Function 블록이나 Simulink 블록을 사용하십시오.
