\mfracfrom nccmath(중간 크기 분수, 표시 스타일의 ~80%), \smashoperatorfrom mathtools및 가장 긴 행에 대한 환경 명령을 사용하면 aligned모두 한 줄에 들어갈 수도 있습니다.

Note에는 환경과 스위치 nccmath도 있습니다 .medsize\medop

eqnarray*더 이상 사용하지 말아야 할 를 align*from 으로 대체 amsmath하고 \left[\begn{array} … \end{array}\right]구성을 더 간단한 으로 대체했습니다 \begin{bmatrix} … \end{bmatrix}.
