Java 패키지 연동

컴파일된 MATLAB^® 함수를 Java^® 애플리케이션에 연동

MATLAB Compiler SDK™를 사용하여 컴파일된 MATLAB 함수를 Java 애플리케이션에 연동하려면 MATLAB Runtime을 초기화하는 API, 컴파일된 MATLAB 함수를 MATLAB Runtime으로 로드하는 API, Java와 MATLAB 사이의 데이터 전달을 관리하는 API를 조합해서 사용해야 합니다.

Java 패키지와 애플리케이션은 대규모 엔터프라이즈 환경이나 웹 환경의 애플리케이션을 위한 이식 가능하고 확장 가능한 솔루션을 제공합니다. 생성된 패키지를 MATLAB Runtime이 설치된 엔터프라이즈 환경이나 웹 환경에 배포할 수 있습니다.

Java 원격 메서드 호출(RMI)은 Java 객체가 다른 Java 가상 머신(JVM)에서 실행되는 객체를 호출할 수 있도록 하는 API 세트입니다. 클라이언트-서버 애플리케이션, 분산 애플리케이션, 웹 애플리케이션을 개발하려면 RMI를 사용하십시오. 이러한 애플리케이션의 경우 MATLAB 함수를 직접 호출하는 애플리케이션의 일부만 MATLAB Runtime이 필요합니다. 애플리케이션의 다른 부분은 네이티브 Java 데이터형을 사용하여 작업할 수 있습니다.
