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...

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...
