사이파이 선형대수학
매트릭스가 무엇인지 말해줄 순 없네. 직접 봐야 하지.
- 모피어스, 영화 <매트릭스> 등장인물
이번 장에서는 선형대수학의 우아한 사용법을 소개한다. 사이파이 패키지에서 컴퓨터 과학의
기초를 형성하는 선형대수학을 사용해보자.
6.1
선형대수학 기초
이 책은 독자가 선형대수학 개념에 익숙하다고 가정한다. 선형대수학은 벡터 (숫자가 정렬된
집합)를 포함한다는 것과 벡터와 행렬 (벡터의 집합 )을 곱하여 변형시킨다는 것을 알아야 한
다. 이 개념에 대해서 익숙하지 않다면 이 장을 읽기 전에 선형대수학에 대한 기초 서적이나 인
터넷 자료를 읽어야 한다. 『선형대수학과 그 응용
