matlab.io.hdfeos.sw

HDF-EOS 주사(Swath) 파일에 대한 로우 레벨 액세스(Low-level Access)

설명

이 MATLAB^® 함수를 사용하려면 HDF-EOS 라이브러리 C 인터페이스를 잘 알고 있어야 합니다. 대개의 경우 MATLAB 함수의 구문은 상응하는 HDF-EOS 라이브러리 함수의 구문과 유사합니다. 이러한 함수는 matlab.io.hdfeos.sw 네임스페이스로 구현됩니다. 이 네임스페이스를 사용하려면 함수 이름 앞에 네임스페이스 경로를 지정하거나, 가져오기 함수를 사용하여 현재 가져오기 목록에 네임스페이스를 추가한 후 함수를 호출하십시오. 예를 들면 다음과 같습니다.

import matlab.io.hdfeos.*
fileId = sw.open(filename);
