本文介绍了在C和Objective-C中使用不同方式初始化对象的方法，包括字符数组、字典和数组的初始化。通过具体的代码示例展示了如何利用这些技术进行内存分配及对象创建。

@(对象)：对象初始化

char *answer = malloc(size);//字符数组

NSString *currentMachine = @(answer);

@{key:value}:字典初始化

@[x1,x2,x3,...]:数组初始化

Vue是一套用于构建用户界面的渐进式框架。 渐进式就跟这个图片一样，开发可以根据需求，逐渐递增所要的方式，但每个方式有不是依靠行特别强 Vue 的核心库只关注视图层，不仅易于上手，还便于与第三方库或既有项目整合。 库是一个模块，而Vue是一套架构，会基于自身特点向用户提供一套相当完整的解决方案，而且控制权在框架本身；对项目的侵入性较大，使用者要按照框架所规定的某种特定规范进行开发，项目如果需要更换框架，则需要重新架构整个项目。响应式的数据绑定：当数据发生改变，视图可以自动更新，可以不用关心dom操作，而专心

这个函数主要就是进行帧到地图的匹配，通过点到面、点到线的距离距离最小作为优化目标。LOAM中雅阁比矩阵推导其实还是过于复杂了，可以使用进行误差扰动来计算雅阁比矩阵，姿态使用失准角（李代数）模型推导更为简单。

Android利用包含排斥原理求x~y之间不能被x1,x2,x3.....xn整除的个数

前言        撰写此博客，也是源于一道离散数学题。求1到1000之间（包含1和1000在内）既不能被5和6，也不能被8整除的数的个数。在第一次写的时候，用Java很简单的实现了上述讲到的数学问题。可在实际应用中，我们利用包含排斥原理来筛选数据，这些数据和筛选的规则往往不是固定的，所以，突发奇想：能不能利用包含排斥原理求x~y之间不能被x1,x2,x3.....xn整除的个数？本文为了让效果更...

KeyError: &#39;Duplicate keys in Model.addVars()&#39;
12-08
这个错误信息“KeyError: &#39;Duplicate keys in Model.addVars()&#39;”通常出现在使用PuLP库进行线性规划时。错误的原因是Model.addVars()方法中传入了重复的键。以下是一些可能的原因和解决方法： 1. **重复的变量名**： 确保在调用Model.addVars()时，传入的变量名是唯一的。重复的变量名会导致这个错误。 2. **数据结构问题**： 检查传入的数据结构，确保没有重复的键。例如，如果使用字典或列表来生成变量，确保这些数据结构中没有重复的键。 3. **生成变量的逻辑问题**： 如果变量名是通过某种逻辑生成的，检查生成变量的逻辑，确保没有逻辑错误导致重复的变量名。 以下是一个示例代码，展示了如何正确地使用Model.addVars()方法： ```python import pulp # 创建一个线性规划问题 prob = pulp.LpProblem("Example Problem", pulp.LpMinimize) # 定义变量，确保没有重复的键 variables = [&#39;x1&#39;, &#39;x2&#39;, &#39;x3&#39;] var_dict = pulp.LpVariable.dicts("var", variables, cat=&#39;Continuous&#39;) # 添加目标函数 prob += pulp.lpSum([var_dict[i] for i in variables]) # 添加约束条件 prob += var_dict[&#39;x1&#39;] + var_dict[&#39;x2&#39;] >= 10 prob += var_dict[&#39;x2&#39;] + var_dict[&#39;x3&#39;] >= 8 # 求解问题 prob.solve() # 输出结果 for v in prob.variables(): print(v.name, "=", v.varValue) ``` 在这个示例中，变量名是唯一的，因此不会引发KeyError错误。
