Simulink용 System object 사용자 지정하기

MATLAB System 블록에 사용할 System object™ 사용자 지정

MATLAB System 블록을 사용하면 MATLAB^®에서 정의한 System object를 Simulink^®에서 블록으로 사용할 수 있습니다. 블록 모양 또는 출력을 제어하거나 For Each Subsystem에서 System object를 사용하도록 활성화하려면 제공된 구현 메서드를 사용하여 System object를 사용자 지정하십시오. System object를 정의하는 방법에 대한 자세한 내용은 기본 System object 정의하기 항목 또는 System object 항목을 참조하십시오.
