MATLAB의 png 파일에 출력 수치 저장

Question

별도의 수치 모델링 소프트웨어 (압력 파일)에서 얻은 텍스트 데이터의 일부 2D 이미지를 플로팅 한 코드가 있습니다. 이 코드는 시간 순간 및 시각화 제한을 묻고 나를 그림으로 반환합니다.

내가 원하는 것은 시간 간격 (2s에서 20s까지)과 "시간 단계"(1s)를 제공 할 입력을 요청하면서 시각화가 모든 수치. 그런 다음 19 자 정도의 정보를 제공해야합니다. 또한 출력을 자동으로 .png 파일로 저장하는 것이 좋을 것입니다.

Answer 1

는 그냥 saveas function를 사용합니다. 사용 예제 :

saveas(gcf,'figure.png'); 

또는 직접 참조로 :

fig_1 = figure(); 
% your plotting... 
saveas(fig_1,'figure_1.png');
