[인프런|1.6] Linear Equations in Linear Algebra | Linear Equations in Linear Algebra
1.6 Linear Equations in Linear Algebra - linearly dependent / independent The set {v1, ... , v2} in R^n is said to be linearly dependent if there exist weights c1, ... , cp, not all zero, c1v1+...+cpvp = 0 => Ax = 0 homegeneous system 1개라도 non zero 이면 consistant이고 즉, homegeneous system이다 그러면서 free variable이 있는 경우 이므로 dependent이다 ex1) v1=[[1], [2], [3]], v2=[[4], [5], [6]], v3=[[2], [1], [0]] 2번째..
