어떻게 할 수 MATLAB을 사용하여 다음과 같은 테이블을 만드시겠습니까?
테이블의 데이터는 PMV의 값이다. 그것들은 MATLAB의 개별 계산으로부터 얻어졌습니다.
'PMV_evaluator'와'Icldyn_7730' 함수가하는 것을 추가하십시오. 코드에 자세한 내용을 입력하십시오. – Umar
테이블을 어디에서 구합니까? 파일에? 변수 편집기에서? 명령 창에서? 'table' 함수의 문제점은 무엇입니까? 시도해 봤어? – thewaywewalk
매트릭스와 matlab의 테이블 함수를 사용하려고 생각했지만 구성을 올바르게 사용하는 방법을 모르겠습니다. 훨씬 간단하기 때문에 Excel에서 염두에 두었던 테이블을 만들었습니다. Matlab에서 동일하게하고 싶습니다. 도와 주실 수 있습니까? –
