多视点几何学中从P中提取出K,R例如P = K*R*[eye(3) -t]以及从两个相机矩阵得到单应矩阵(Multiview geometry extracted from the P K, R such as P = K* R* [eye (3)-t])

实现圆的绘制在绘制时要添加相关的参数，以免出错。(to draw a circle,this circle can be in special type,it can be drawn easily with less time be cost.)

说明：  实现数据误差的剔除、修正，曲线拟合，平缓。(Eliminate data errors, correction, curve fitting, flat.)

蓄电池放电模型,经过调试可以使用，希望对大家有帮助。(Battery discharge model, after debugging can be used, I hope to help you.)

MODULATION AND DEMODULATION WITH NOISE AND AGAIN EXTRACTING IT FROM THE SIGNAL

matlab经典的三十个智能算法代码，你懂得，绝对经典。。。(matlab classic thirty intelligent algorithm code, you know, an absolute classic. . .)

Jerk系统产生的混沌模拟信号，并对其进行了离散化处理 (Chaos Jerk analog signal generated by the system, and its discrete processing)

说明：  rung-kutta 4 he inputs func, x0 and y0 define an IVP y = func(x,y), y(x0) = y0. This provides an approximation to y(x0:h:xn) using fourth-order Runge-Kutta method with step size h

使用matlab软件实现鲁棒控制技术，对电力系统中电频率控制能很好的实现(Using matlab software robust control technology, electric power system frequency control can achieve good)

说明：  负荷频率控制（LFC）是调整系统的频率达到额定值（如50HZ）或/和维持区域联络线交换功率为计划值。频率稳定是电力系统电能质量的一个重要指标。负荷的任意突然变化都有可能导致系统间联络线交换功率的偏差及系统频率的波动。因此，为保证电能质量，需要一个负荷频率控制(load frequency control,LFC)系统，该系统的目的是将系统频率维持在标称值并且尽可能使控制区域之间的未计划的联络线交换功率最小。(Load frequency control (LFC) is to adjust the frequency of the system to reach the rated value (such as 50 Hz) or / and maintain the exchange power of the regional tie line to the planned value. Frequency stability is an important index of power quality in power system. Any sudden change of load may lead to the deviation of power exchange between tie lines and the fluctuation of system frequency. Therefore, in order to ensure the power quality, a load frequency control (LFC) system is needed. The purpose of the system is to maintain the system frequency at the nominal value and minimize the unplanned tie line exchange power between the control areas.)
