linear algebra的核心就是向量的两种操作:addition和scalar multiplication。使用这两种操作就可以产生一个“linear combination”。例如,有两个向量v和u,通过addition可以得到向量v+u,再给v和u分别乘上一个scalar c和d,可以得到cv+du,这就是一个linear combination cv+du Subspaces spanned by a set 一个空间有无...

3. Vector spaces and subspaces 3.1 Space of vectors Rn consists of a whole collection of vectors with n components. If the components are complex numbers, use Cn Z (The vector space that consists only of a zero vector) is the smallest possible vector space with 0-dimension. A subspace of...
Linear algebra is the branch of mathematics concerning vector spaces and linear mappings between such spaces. It includes the study of lines, planes, and subspaces, but is also concerned with properties common to all vector spaces. The set of points with coordinates that satisfy a linear equation...
本节的将引入向量空间(vector spaces)和子空间(subspaces)。 转置Transposes 矩阵的转置就是把它的行看成列,列看成行得到一个新的矩阵,(A^{T})_{ij}=A_{ji}。 对于一个对称矩阵 A ,其转置等于自身。矩阵乘积的转置满足:(AB)^{T}=B^{T}A^{T}. 对于任意矩阵 R ,R^{T}R一定是对称矩阵:(R^{T...
