답변 감사합니다. 명쾌하게 이해되었습니다. 제가 오해가 있었던 부분이 있었네요~ 빠른답변 다시한번 감사합니다!

1.8절 질문있습니다.

우선 친절한 답변 너무 감사합니다.
Q1)에서 조금더 덧대어 질문드리고싶은데요.&nbsp;
<span style="color: #000a12; font-family: 'Spoqa Han Sans', 'Apple SD Gothic Neo', BlinkMacSystemFont, -apple-system, 'Segoe UI', Roboto, Oxygen, Ubuntu, Cantarell, 'Fira Sans', 'Droid Sans', 'Helvetica Neue', Helvetica, Arial, sans-serif; font-size: 16px; background-color: #ffffff;">A = [a1, ... , an]&nbsp; / A 행렬을 이렇게 표현한 것은 원래 a1열에는 a11~am1까지 있는 데 그것이 생략된 형태라고 봐야할까요? 아니면 a1의 벡터가 a11~am1을 다 포함하고 있어서 굳이 길게 표현안하고 그냥 a1을 벡터의관점에서 a1이라고 쓴 것인가요?

그리고 1.4절에서&nbsp;
