它们被称为在 I 上线性无关(linearly independent),若方程 c_1y_1(x) + c_2y_2(x) = 0 仅在c_1=c_2=0 时成立 反之,则是线性相关的(linearly dependent) (对于有限多个函数的情况,都可以使用这个定义) 仅针对两个函数的情况,这里我们介绍一个判断两函数是否线性相关的简单方法 若\frac{f_1(x)}...
..vn 线性独立(linearly independent);反之,如果找得到不全为0的一组系数 ai 使得a1v1+a2v2+...+anvn=0 ,我们就说 v1,v2...vn 线性不独立(linearly dependent)。 一个特殊情况:空列表 {} 是线性独立的。Span({})={0}。 一组线性独立的矢量去掉任意一个,剩下的矢量依然线性独立;一组线性独立矢量...
linear independent判断 两个向量为线性无关的条件是,如果向量x、y中的任意一个向量不能表示为另一个向量的线性组合,则这两个向量是线性无关的。换句话说,如果方程ax + by = 0只有当a = b = 0时才成立,则向量x、y是线性无关的。 可以通过计算行列式来判断向量的线性无关性。设向量x=[x1, x2, ......
The meaning of LINEAR INDEPENDENCE is the property of a set (as of matrices or vectors) having no linear combination of all its elements equal to zero when coefficients are taken from a given set unless the coefficient of each element is zero.
Thus, S={v1,v2} is linearly dependent. Equivalently, we have: A set of two nonzero vectors is linearly independent if and only if neither of the vectors is a scalar multiple of the other. Notice that in the argument above, we showed that if one of two nonzero vectors is a scalar ...
well defined means the result of any operation is unique. You can view the operation as a mapping, and well define means that any element can only be mapped to a unique element with the rules of operation, we can deduce the properties of the algebraic system ...
1、在向量空间V的一组向量A:a1，a2，am。2、如果存在不全为零的数k1，k2，km。3、则称向量组A是线性相关的，否则数k1，k2，km全为0时，称它是线性无关。4、由此定义看出a1，a2，am是否线性相关，就看是否存在一组不全为零的数k1，k2，，km使得上式成立。即是看k1a1加k2a2加kmam等于0...
