这几天,根据buddy指定的任务,要分享一点angular JS的东西.对于一个在前端属于纯新手的我来说,Javascript都还是一知半解,要想直接上手angular JS,遇到的阻力还真是不少.不过我相信,只要下功夫,即使是反人类的设计也不是什么大的问题. Okay,废话不多说.为了弄明白angular JS为何物,我先是从Scope开始.那么什么是Scope呢?借用官方文档的一段话: “scope is an object that refers to the applicati…

OpenCASCADE Root-Finding Algorithm eryar@163.com Abstract. A root-finding algorithm is a numerical method, or algorithm, for finding a value x such that f(x)=0, for a given function f. Such an x is called a root of the function f. In OpenCASCADE math…
2ed, by Timothy Sauer DEFINITION 1.3A solution is correct within p decimal places if the error is less than 0.5 × 10$^{−p}$ .-P29Bisection Method的优点是计算次数(step)是确定的(interval<精度).后面介绍的算法的interval是不确定的, 所以什么时候结束计算呢?不知道.所以定义“stopping criteria’’来决定什么时候结束…
