然而,一般方程系统不是这种简单的形式.幸运的是,有一种建设性的算法方法将任何线性方程组转化为这种特别简单的形式:高斯消除.高斯消去的关键是线性方程组的初等变换,它将方程组转化为简单形式。 然后,我们可以将这三个步骤应用于简单的for 我们刚才在(2.38)中的示例中讨论了这一点) 2.3.2 Elementary Transformations...
[Week 1] Machine-learning Notes 4 ——Linear Algebra(一些线性代数基础) 矩阵实际上是二维数组的另一个名字:而维度(Dimension of matrix)就是矩阵的行数乘以列数(一般分开说,比如4行2列,不说8维矩阵,只说4X2的矩阵,意思就是维度是4X2维,即4X2matrix,)。 但是矩阵在书写上也有些不同,如下: Paste_Image....
【摘要】 Linear Algebra 线性代数 在形式化直观概念时,常用的方法是构造一组对象(符号)和一组规则来操纵这些对象。 这被称为代数。 线性代数是研究向量和某些代数规则来操纵向量。 我们中的许多人从学校知道的向量被称为“几何向量”,通常用字母就加上上方的一个小箭头表示,例如... Linear Algebra 线性代数 在...
