System object를 사용하여 블록 구현하기

MATLAB System 블록을 사용하여 Simulink^®에서 System object™ 사용

MATLAB System 블록은 System object를 사용하여 Simulink에서 MATLAB^® 알고리즘을 구현합니다. MATLAB System 블록을 사용하려면 먼저 블록과 연결할 System object가 있어야 합니다. System object는 동적 시스템 구현과 시뮬레이션을 위해 특별히 설계된 특수한 종류의 MATLAB 클래스입니다. System object 구현 및 작성에 대한 자세한 내용은 System object 생성하기 항목을 참조하십시오.

Integrate Python GPS Text Message Parsing Algorithms in Simulink

Parse text messages in NMEA GPS format using Simulink® string blocks and Python®. NMEA sentences are used for communication between marine devices, and the model in the example decodes RMB and RMC sentences in NMEA. RMB is the sentence for the recommended navigation data for GPS. RMC is the sentence for the recommended minimum data for GPS sentences.
