被FunctionCompile的函数,输入能用"PackedArray"就不用"ListVector",运行效率会提高很多。 2. 确定C++代码中函数的输入、输出类型 在FunctionCompile中对PackedArray和CArray进行类型转换,不仅麻烦,编译速度慢,运行效率也低。 所以C++代码的输入、输出类型应为MTensor(即FunctionCompile中的PackedArray),这样可以避免在Fun...
Arc Length Function Curvature The Normal and Bionormal Vectors Torsion 这部分的内容,精华主要集中在Arc Length(弧长)和Curvature(曲率)这部分内容里面。关于Vector Functions的定义,求导和积分都应用在这部分内容里面。主要麻烦的地方在于有很多代数符号以及它们对应的实际含义得弄清楚。掌握了Vector Functions部分的内容...

一种解法是function overloading。对vector和array分别编写find()。除此有没有能够支持这两种容器的通用find()呢? 把大问题切割成难度较小的子问题,逐一求解,是一种思路。分隔成的两个问题: 1,vector传入find()的是元素,而不用指明该vector。 2,array传入find()的是元素,而不用指明该array。
A9:第一个问题日志有没有做加密是想问日志中的一些敏感信息字段能否加密吗?vector的 Transform 过程中有很多的方法,可以针对某一些特定字段做处理,例如redact这个VRL function就可以对敏感字段的数据做mask处理。 第二个问题行业内有没有安全存储的要求? 日志在进入到鸿鹄系统以后是以我们特定的格式存储的。我不太确定...
input vectors is < 90°. If you need two vectors to be < x degrees apart, thendot > cos(x°)must be true, where cos(x°) is a constant. Note that this way, the dot product allows to check the angle between two vectors without calling the rather expensive cosine function at run...
Clear content Removes all elements from the vector (which are destroyed), leaving the container with a size of 0. A reallocation is not guaranteed to happen, and the vector capacity is not guaranteed to change due to calling this function. A typical alternative that forces a reallocation is ...
