The Matrix Cookbook，高清书籍+讲解+书签，推导每一个公式加上详细的讲解

矩阵求导详细手册-求导运算公式表文献及-PPT，文献为斯坦福大学数学系推导和总结的矩阵求导运算表，PPT为一些矩阵求导运算规则。是我在看机器学习线性回归推导时时候要用到的内容，网上比较后找了这两个质量比较高的资料，超值了。

MATLAB的简单应用 输入方式: （1）求一阶导数 dy=diff(y) 或： dy=diff(y,v) （2）求高阶导数 dy=diff(y,n) 或：dy=diff(y,v,n)

该文档总结了矩阵对矩阵、矩阵对向量、向量对矩阵、向量对向量、元素对矩阵、元素对向量的求导法则，非常有用！
