하위 그림으로 캡션을 하위 그림으로 표현

Question

저는 LaTeX를 처음 사용합니다. 내 질문의 틀을 어떻게 구성해야 할지 잘 모르겠습니다. 하지만 이해할 수 있도록 프레임을 지정하겠습니다.

하위 그림을 만들고 싶지만 캡션은 다음과 같아야 합니다.

caption of subfigure a-1 caption of subfigure a-2

caption of subfigure b-1 caption of subfigure b-2

                 `caption  of entire figure`

하위 그림을 사용해 보았으나 계속해서 가 발생 a,b,c,d하지만 위에서 언급한 대로 이름을 지정해야 합니다(a-1, a-2, b-1, b-2). 내 상황에서는 하위 그림이 다른 페이지에 있을 가능성이 있습니다.

Answer 1

subequations이는 와 동일한 아이디어를 사용합니다 amsmath.
