此代码是关于稀疏矩阵。我表示稀疏矩阵为结构。它还可以做稀疏矩阵加法。如果你读了这段代码然后你可以了解有关内存分配、 指针和结构中的应用。稀疏 matrix 元素几乎为 0，所以如果你将它定义为 2 的三维数组，然后它会浪费内存。解我的想法是，使用结构.通知： 我是韩国的所以所有的文件和在 c 文件上的评论由朝鲜语写的。

四轮转向车辆操纵稳定性仿真分析，首先建立二自由度四轮转向车辆运动微分方程，求解出横摆角速度、质心侧偏角、侧向加速度的传递函数，然后在MATLAB环境中通过M语言编写仿真软件对传递函数的时域与频域特性进行计算，最后将仿真数据与前轮转向车辆仿真数据进行对比分析。(The simulation analysis of steering stability of four-wheel steering vehicles first establishes the differential equation of motion of two-degree-of-freedom four-wheel steering vehicle, and solves the transfer function of yaw angular velocity, centroid side yaw angle and lateral acceleration, and then passes the medium language in MATLAB environment. The simulation software is written to calculate the time domain and frequency domain characteristics of the transfer function. Finally, the simulation data is compared with the front wheel steering vehicle simulation data.)

我的作业，没什么更好的给大家 现在就拿这个了 以后会有好的哦-my work, and there is nothing better for everyone now Take the future there will be a good, oh

几何体的体积表面积计算-geometric size of the surface area calculation

牛顿－拉夫逊法潮流计算 基本步骤： 　　（1）形成节点导纳矩阵 　　（2）将各节点电压设初值U， 　　（3）将节点初值代入相关求式，求出修正方程式的常数项向量 　　（4）将节点电压初值代入求式，求出雅可比矩阵元素 　　（5）求解修正方程，求修正向量 　　（6）求取节点电压的新值 　　（7）检查是否收敛，如不收敛，则以各节点电压的新值作为初值自第3步重新开始进行狭义次迭代，否则转入下一步 　　（8）计算支路功率分布，PV节点无功功率和平衡节点柱入功率。(Newton-Raphson method flow calculation basic steps : (1) formation of nodal admittance matrix (2) to set up the initial node voltage U, (3) the initial node-generation-related demand. calculated that the constant term formula Vector (4) nodes will be incorporated into the initial voltage-seeking, calculated Jacobian matrix elements (5) solving that equation, seek to amend the vector (6) to strike a new node voltage value (7) to check whether convergence, if not restrained. concentrated in the nodes of the new voltage as the initial value since the first three steps to re-start the narrow iterations. Otherwise, turn into the next (8) Calculation branch power distribution, PV nodes reactive power and balance-node into power.)
