A brief introduction to square roots The ins and outs of the Python square root function,sqrt() A practical application ofsqrt()using a real-world example Knowing how to usesqrt()is only part of the equation. Understanding when to use it is equally important. Now that you know both, go...
用二分法定义平方根函数(Bisection method Square Root Python) Python里面有内置(Built-in)的平方根函数:sqrt(),可以方便计算正数的平方根。那么,如果要自己定义一个sqrt函数,该怎么解决呢? 解决思路: 1. 大于等于1的正数n的方根,范围肯定在0~n之间;小于1的正数n的方根,范围肯定在0~1之间 2. 用二分法(Bisecti...
牛顿法(Newton’s method)又称为牛顿-拉弗森法(Newton-Raphson method),是一种近似求解实数方程式的方法。(注:Joseph Raphson在1690年出版的《一般方程分析》中提出了后来被称为“牛顿-拉弗森法”的数学方法,牛顿于1671年写成的著作《流数法》中亦包括了这个方法,但该书在1736年才出版。) 之前的一篇博客中提到的二...
从统计学的角度来看,有许多关联性测量方法,例如卡方检验(chi-square test)、费舍尔精确检验(Fisher exact test)、超几何检验(hypergeometric test)等。它们通常用于其中一个或两个变量为有序(ordinal)或名义(nominal)变量的情况。 注意:相关性是一个技术术语,而关联性不...
